Jeb Bush is hardly new to global travel.

As a high school student, Mr. Bush studied in Mexico. Early in his career, he lived in Venezuela. As governor of Florida and after, he has taken dozens of international trips.

This week, on the eve of his expected June 15 announcement for president, Bush is on the road again 鈥� first Germany, then Poland and Estonia.

Why does Bush feel the need to do this? And why now?

First, it鈥檚 one thing to have traveled abroad as a governor 鈥� promoting trade with your state 鈥� and then as a private citizen. But it鈥檚 quite another to be auditioning to become leader of the free world and impress upon American voters that you are comfortable dealing with world leaders.

鈥淥ne motivation is to reinforce the essential message from the Jeb Bush team that he鈥檚 the grown-up in the race,鈥� says Gil Troy, a presidential historian at McGill University in Montreal. 鈥淭here鈥檚 something about being a statesman on foreign policy that proves you have grown-up street cred.鈥�

Mr. Troy also sees the trip as a smart way of getting media coverage that鈥檚 different from just fundraising and political positioning. Bush鈥檚 campaign rollout has been rocky, as he has grappled to escape the shadow of the previous Presidents Bush, his father and brother. On Monday, .听听

鈥淭he trip is a clever attempt to reframe and put him in a more presidential mode,鈥� says Troy.

Foreign policy and national security are growing in importance as campaign issues, particularly for Republican voters, as President Obama struggles with the rise of the Islamic State and Russia鈥檚 aggression in Ukraine. Bush is expected to lay out his differences with both Mr. Obama and the Democratic presidential front-runner, Hillary Clinton. Mrs. Clinton鈥檚 failed 鈥渞eset鈥� with Russia during her time as secretary of State is a liability in her candidacy.

Bush begins his trip Tuesday in Berlin, where he will address an economic conference of the ruling 海角大神 Democratic Party, speaking right before Chancellor Angela Merkel. In Estonia and Poland, both NATO members alongside Germany, Bush will meet with government and business leaders. The goal of the meetings is to 鈥渂etter understand the concerns and views of our European allies on a range of topics,鈥� including Russia, terrorism, trade, and economic growth, Bush spokeswoman Allie Brandenburger told NBC News.聽

But Iraq will also loom large during the trip. Germany remains firmly opposed to the Iraq War launched in 2003 by Bush鈥檚 brother, former President George W. Bush. Perhaps the worst week in Jeb Bush鈥檚 unannounced campaign came in May, when he struggled for days on the question of whether he would have launched the war, knowing that Iraq did not in fact have weapons of mass destruction.

In contrast, one of Bush鈥檚 top rivals for the Republican nomination 鈥� fellow Floridian and former prot茅g茅 Sen. Marco Rubio 鈥� has risen in the polls as he has made foreign policy a key part of his campaign, including his service on the Senate Foreign Relations Committee.

Bush delivered a major address on foreign policy in February, but was light on specifics. The most memorable line was 鈥淚鈥檓 my own man,鈥� a reference to the other Presidents Bush. While in Europe, he is expected to elaborate more on what a Jeb Bush foreign policy doctrine might look like.

鈥淚 think what鈥檚 important here is not the contrast with the others, but in defining his own clear doctrine that reflects a clear strategy for the US,鈥� says Republican pollster David Winston.

In modern politics, trips abroad by presidential candidates are virtually a requirement, though their nature has changed. Time was when contenders would quietly go overseas to 鈥渓ook, learn, and listen,鈥� says Troy, the McGill professor. Some, like President Dwight Eisenhower and 1996 GOP nominee Bob Dole, got their foreign experience in World War II.

Then Obama raised the bar, with his big splashy address in Berlin in 2008, to 200,000 people. Now candidates heading to Europe can鈥檛 escape the media klieg lights, and most have stumbled. In 2012, GOP nominee Mitt Romney went to London and insulted his hosts when he cast doubt on the city鈥檚 readiness to host the Olympics.

This cycle, London has snared many a Republican hopeful. Wisconsin Gov. Scott Walker, expected to announce his campaign soon, went to London unprepared to answer questions on his beliefs 鈥� including whether he believed in evolution. New Jersey Gov. Chris Christie, also expected to announce soon, stirred up headlines when he said that parents should have choice on whether to vaccinate their children. Louisiana Gov. Bobby Jindal, who announces his campaign June 24, raised the ire of London Mayor Boris Johnson in January when he said that some parts of Britain and Europe were Muslim 鈥渘o-go zones.鈥�

Bush isn鈥檛 going to London on this trip, and maybe that鈥檚 wise. Or perhaps he should go to London and prove that he can answer questions of the feisty British press and come out unscathed.

The reality, though, is that doing well on a foreign trip usually doesn鈥檛 matter much to voters. Typically it鈥檚 the gaffes that get big coverage, and Bush doesn鈥檛 need any more negative headlines.
