So what constitutes a campaign contribution?

Mark Zuckerberg is a big Obama backer. Facebook is going to host a forum for Obama to take questions from Facebook users. I have no problem with Facebook doing this, but will Facebook do this for all the Republican candidates? Facebook is supposedly going to select questions to forward to Obama. Will they select questions in the same way if a Republican candidate holds a forum on Facebook?

Hoping to grab some high-tech luster and begin filling the campaign war chest he'll need in 2012, President Barack Obama will visit Facebook this month for an online town hall event with CEO Mark Zuckerberg before going to San Francisco for a series of pricey fundraisers, including a $35,800-a-plate dinner hosted by Salesforce.com CEO Marc Benioff.
Obama, who announced Monday he would seek re-election, is using the two-day visit to Silicon Valley and San Francisco as an initial lap of the 2012 presidential campaign. He is expected to return to the Bay Area multiple times before the election.
Facebook and the White House jointly announced Tuesday that Obama will visit the Palo Alto headquarters of the social network on April 20, where the president will hold a special "Facebook town hall" event that will stream live over Facebook and the White House website, starting at 1:45 p.m. Zuckerberg and Facebook Chief Operating Officer Sheryl Sandberg will moderate and sit onstage with the president, in front of an audience of about 1,000 Facebook employees, small-business leaders and Silicon Valley entrepreneurs. . . .
