#AskBobby brings Jindal mockery and criticism. Chris Christie's hashtag also brought out the Twitter trolls. Do campaigns understand social media? Win McNamee/Getty Images

New Jersey Gov. Chris Christie wasn't the only Republican presidential candidate to venture onto Twitter and get burned for doing so on Tuesday. Christie, who saw his campaign slogan "#TellingItLikeItIs" taken over by critics after his campaign announcement Tuesday morning, was joined by Louisiana Gov. Bobby Jindal. The super PAC associated with Jindal's campaign invited social media attention with "#AskBobby," which they tweeted just before Jindal began his first town hall meeting in Waukee, Iowa.

The Christie and Jindal campaigns don't seem to have understood that online anonymity draws a different kind of response than an Iowa town hall. In Waukee, people stood up and asked their questions in person. On Twitter, avatars of Donald Trump with a giant orange moustache, identified as "Donald J. Drumpf," are free to ask and say anything, including ponder whether or not your birth certificate is real.

The #AskBobby campaign was a hit and blew up with more than 17,000 tweets mentioning the tag in the first few hours. It just didn't appear to be a hit for Jindal himself. Trolls questioned "Bobby" on things all along the spectrum. One, apparently referring to his views on evolution, asked whether or not anyone can "pet a dinosaur or just Jesus."
