Obama 2012 campaign joins Instagram on eve of Iowa caucuses

As Republicans focused on the Iowa caucuses and President Barack Obama made a pitch to Iowans of his own over streaming video on Tuesday, the Obama 2012 reelection campaign took its message to Instagram. Obama's campaign team, which is also looking to reach voters on Tumblr and Google+ (along with a few Republican rivals), has posted two photos thus far, both of the President speaking with Iowa's caucus voters via video chat, making his case for another term in the White House.
