The liberal base will give its full support to President Obama in 2012 despite its frustration over the lack of progress on certain key issues, former White House senior adviser David Axelrod said Monday.

Axelrod — who will serve as a top aide to Obama's reelection campaign — acknowledged that "people can be hardest on their friends," but said that the Obama campaign has already received a "tremendous" volunteer response. He added that the choice between Obama and the Republican candidate will "galvanize" voters around the president.
