It鈥檚 no coincidence that President Obama chose Wednesday to make a surprise appearance on Reddit, a popular Internet social news site. The president took questions from users in the site鈥檚 鈥淎sk Me Anything,鈥� or AMA, forum 鈥� and in the process, siphoned off some attention from the GOP Convention in Tampa.

Along with the pomp and ceremony of the official convention programming comes a more under-the-radar tradition: the numerous ways the rival party concocts to undercut that programming and message.

In the past, there鈥檚 been at least a partial, mutually respected truce during conventions, in which the rival presidential candidate himself takes the week off from campaigning, often using the convention days to grab a brief vacation. But that tradition was eroded in 2008, when both then-Senator Obama and Sen. John McCain scheduled some campaign events during the other鈥檚 convention.

This year, the Democratic insurgency is in full swing, with a roster of heavy-hitting surrogates launching defensive attacks from the Democratic war room just blocks from the convention center, and Obama himself campaigning to an unprecedented degree during the convention on college campuses and in swing states. Until hurricane Isaac threatened, Vice President Biden was even scheduled to be in Tampa, which would have been unheard of.聽

The advent of super PACS and nonstop ads playing in swing states over the summer 鈥渉as frontloaded the entire campaign insurgency, because no one wants to let their foot off the pedal in terms of keeping up the drumbeat for their viewpoint,鈥� says Susan MacManus, a political science professor at the University of South Florida.

Here in Tampa, a deep roster of well-known Democrats have been chatting up reporters, holding press conferences, and even infiltrating the Tampa Bay Times Forum (鈥淭here were a lot of double-takes,鈥� former Obama Press Secretary Robert Gibbs reportedly said afterward).

Mr. Gibbs is one of the most familiar Democratic faces hiding amid the hordes of Republican ones in Tampa, but he鈥檚 far from alone. Maryland Gov. Martin O鈥橫alley is here too, as is Los Angeles Mayor Antonio Villaraigosa, chairman of the Democratic National Committee, Illinois Sen. Dick Durbin, Obama鈥檚 campaign cochair, and Rep. Chris Van Hollen of Maryland, who will be the stand-in for the GOP vice presidential nominee in Biden鈥檚 debate preparations.

They鈥檙e available to rebut all the GOP spin, and press conferences each day in the Democratic war room have taken on specific themes: why Mitt Romney is bad for the middle class; why Mr. Romney is bad for women; why Romney was bad for Massachusetts.

On Thursday, Democrats were falling over each other to refute the many claims in vice presidential nominee Paul Ryan鈥檚 speech.

鈥淭here鈥檚 no delicate way to say this. Last night Paul Ryan lied 鈥� repeatedly, knowingly and brazenly,鈥� Obama deputy campaign manager Stephanie Cutter told reporters Thursday. She and other Democrats hammered on Ryan for his statements on Medicare, on the president鈥檚 debt commission, and on the closing of a GM plant in Ryan鈥檚 hometown of Janesville, Wis., implying that Obama broke his promise to plant workers, when it actually closed under President Bush.

The surrogates in town are some of Obama鈥檚 most eloquent defenders, and they鈥檙e ready with memorable quotes to try to counter the cacophony of conservative rhetoric.

鈥淚 heard Governor Christie talk about the importance of truth-telling. I just didn鈥檛 hear any truth-telling out of him,鈥� says Congressman Van Hollen. 鈥淚 don鈥檛 think the American people will think it鈥檚 brave to give another round of tax cuts to the very wealthy, to people like Mitt Romney, at the expense of seniors on Medicare who have a median income of $23,000.鈥�

Mayor Villaraigosa, meanwhile, has been taking aim at GOP diversity 鈥� and the roster of speakers in Tampa that overemphasizes Hispanics鈥� and other minorities鈥� role in the party.

"You can't just trot out a brown face or a Spanish surname and expect people are going to vote for your party or your candidate," Villaraigosa said at a press conference Tuesday.

And full-page Democratic ads in the Tampa Tribune have assailed Romney鈥檚 record with the middle class and worked to link Romney and Ryan to Rep. Todd Akin, the Missouri Senate candidate who famously suggested 鈥渓egitimate rape鈥� won鈥檛 lead to pregnancy.

But more notable than the sharp defense game in Tampa, perhaps, is the fact that it hasn鈥檛 just been surrogates talking for Obama this week.

Unlike in the past, when George W. Bush retired to Crawford, Texas, for the week or Bill Clinton retreated to Jackson, Wyo. 鈥� getting a much-needed break along with ceding the spotlight to their opponents for a few days 鈥� Obama has stepped up campaign efforts, especially on college campuses, and grabbed a fair number of Internet headlines Wednesday with the surprise Reddit appearance.

鈥淭here are 70 days left to the election, and we鈥檙e not going to cede any one of them,鈥� Cutter told reporters.

Michelle Obama appeared on David Letterman Wednesday night (she said she hasn鈥檛 been watching the convention), and if Biden had gone to Tampa as planned, that would have been the highest level surrogate to infiltrate a rival party鈥檚 convention.

The Obama campaign says he canceled the trip so that he wouldn鈥檛 get in the way of local security needs for the hurricane, but Professor MacManus wonders if a fear of bad press might have contributed as well.

鈥淚 think one of the reasons they might have pulled back is that it was beginning to look like it was bad form. People didn鈥檛 appreciate it,鈥� she says.

Obama also has nothing planned that would conflict with Romney鈥檚 big speech Thursday night.

With an election this close, though, neither side seemed inclined to let tradition or etiquette get in the way of a chance to score points.

Next week, during the Democratic National Convention, Romney also plans to keep campaigning.
