鈥嬧�婭n 2012, the evidence of how money was changing American presidential elections came in the form of Newt Gingrich lasting longer than most any pundit imagined he would.听

As 2016 approaches, that evidence may聽be coming in the form of Sen. Rand Paul announcing his bid for the presidency聽Tuesday. Or Sen. Ted Cruz doing it last month. Or Sen. Marco Rubio (apparently) doing it next week. Or even in Jeb Bush taking his own sweet time.听

The GOP field is starting to crowd up 鈥� and to grow flush with cash 鈥� despite the eagerness of many Republican Party insiders to avoid the kind of bumptious free-for-all that left Mitt Romney battered and聽looking like he won the GOP nomination by default.听

This time around, the party is angling to create a shortened primary season calendar. It is scheduling fewer debates.听

Don鈥檛 count on a smooth path to the Republican nomination, though.

Like Mr. Gingrich, who was a thorn in Mr. Romney鈥檚 side for longer than the Republican establishment might have wished, this year鈥檚 crop of would-be Republican presidents are filling up on fundraising, making them relatively immune to what the party wants.听

Senator Paul has been cultivating millionaire donors, including the Silicon Valley crowd. Senator Rubio has been chatting up the billionaire Koch Brothers.听Senator Cruz boldly announced that his goal is to raise as much as $50 million,聽amid聽whispers that Jeb Bush could pull in upwards of $100 million by the summer reporting deadline.

What鈥檚 new isn鈥檛 that lots of candidates are running. It鈥檚 that the fund-raising climate can give them higher visibility and potential staying power. With聽$50 million, Cruz could raise no small ruckus.听

As big money rushes into politics in unprecedented sums, the battle lines in the debate over big money seem to be becoming familiar by now. Liberals express outrage over Supreme Court rulings that have opened the door to unlimited sums being spent on politics by groups that can stay virtually anonymous. Conservatives counter that the court merely vindicated free-speech rights sacred since the nation鈥檚 founding 鈥� including that government can鈥檛 tell individuals or groups how much they can spend on speech.听

But those interpretations, while important, don鈥檛 tell the whole story.

They don鈥檛 tell of how the GOP can鈥檛 get the hoped-for coronation of聽an聽establishment candidate if rogue donors don鈥檛 play along. Billionaire casino magnate Sheldon Adelson聽singlehandedly聽kept Gingrich in the game in 2012 with a timely $5 million check on the eve of the South Carolina primary. A similar script could play out again in 2016.

Nor do those interpretations hint at the role big money might be playing in the Republican Party鈥檚 rightward shift.

Indeed, while all seems comparatively in order on the Democratic front, the 2016 election is offering a glimpse at how Washington鈥檚 new era of megamoney is in some ways complicating Republican efforts to retake the White House.

鈥淚t鈥檚 much more of the Wild West out there,鈥� University of Connecticut political scientist Paul Herrson says of the climate for the nascent 2016 campaign.

The numbers are staggering. By some measures, $2.3 billion was spent on the 2012 presidential race 鈥� relatively evenly split between Republicans and Democrats.听In 2016, that appears set to surge again 鈥� with some speculating the total could even聽double.听

鈥婣nd a rising share of the total comes from "outside," from groups are keen to influence the race but pledge not to coordinate with a specific candidate or party.听Republicans dominated on this front in the 2012 cycle, $720 million to $293 million for Democrats, according to the Center for Responsive Politics, which tracks political spending. But the center's聽Sheila Krumholz聽said in that liberal groups have stepped up their "outside" game, too.

"This is a phenomenon across the political spectrum," she said.听

It was this spending that was unleashed by聽landmark Supreme Court rulings, including Citizens United聽in 2010. The ability to raise huge sums of money has for years been a prerequisite of any serious presidential contender. Now, candidates can get more and from more places.听

Mr. Bush appears to be putting off a presidential announcement as long as possible precisely聽so that he can legally participate in raising聽massive amounts聽of outside cash.听That has to stop once a candidate formally announces. (Some legal experts say it should have already stopped, based on Bush鈥檚 all-in behavior.)聽Sizing up such competition, Cruz that 鈥淛eb Bush will shatter every fundraising record ever set.鈥�

But Cruz vows to keep up.听As several Bush groups under the name 鈥淩ight to Rise鈥� rake in money, the other contenders聽aren鈥檛 walking off the field. They聽have formed their own super political action committees or similar聽outside-money groups,聽and are busy turning to big donors themselves.听

鈥淲hen candidates create their own fundraising committees, separate from party, they are no longer accountable to the diverse elements of a party coalition 鈥� but, instead, directly to donors,鈥� Julia Azari, a Marquette University political scientist wrote recently, focused on a group allied with Gov. Scott Walker, one of the presumed 2016 Republican candidates.

Is that a problem? Maybe not, some say. Outside money could actually be a positive, giving rise to a broader array of candidates.听聽

But other analysts disagree. Like them or not, the two parties are the nation鈥檚 main institutions for distilling competing interests and voices into ideas and candidates that voters can respond to with simple up or down choices on Election Day.

While moneyed interests like business groups and聽labor unions聽have always exerted power alongside other activists within the parties, it鈥檚 not clear what layering extra money from the outside accomplishes.

Congress鈥檚 latest聽answer has been to add yet more money to the inside. Now, a wealthy couple can give $3 million directly to party committees in a two-year period, a big boost from limits that had been set in the 2002 McCain-Feingold Act, .听

To be sure, the Republican Party is not being pushed out of the picture.

鈥淢oney in American politics has always been necessary but not sufficient鈥� to win the nomination, says Martin Cohen, a political scientist at James Madison University in Harrisonburg, Va.听

After all, when Bush made an exploratory visit to New Hampshire, his stops included a meet-and-greet hosted by Fergus Cullen, a former chairman of the state鈥檚 Republican Party. While it鈥檚 unlikely any candidate will get the nod without succeeding on the fundraising trail, the parties still hold huge sway on the path to winning their own nominations. Romney鈥檚 eventual triumph in 2012 showed that. 聽

But big money might be making the GOP鈥檚 life more difficult in other ways, too. Though the influences that lead to partisanship are varied, , a group that researches money in politics, concluded that the wealthiest donors 鈥渕ay be pulling Republicans to the political right, acting as a force for a more polarized Congress.鈥�

The foundation matched rankings of lawmaker partisanship with data on the share of campaign funding that each lawmaker gets from the largest 31,385 political donors. (That number of donors represents an elite 鈥�1 percent of the 1 percent鈥� of the overall US population.)

Whether that is a good thing is largely in the eye of the beholder. Back in the 1950s, the two parties drew scholarly criticism for being too ideologically similar. Public opinion polls now find Americans generally worried about the shortage of compromise in Washington.

But as the Republican Party faces a robust crop of candidates courting the right in 2016, the role of big money in fueling the rightward shift of the party 鈥� and financing the candidates who seek to capitalize from it 鈥� appears to be coming into clearer focus.听聽聽
