philly was so pro Obama and dems, it’s pathetic. big dem base. why would he need to campaign there
It's because of his ego. He has to feel relevant somehow. So he campaigns for seats that are already guaranteed locks for the Dems.
A Joni Ernst victory in Iowa would be especially sweet since Moo-chelle campaigned for her opponent Bruce 'Bailey'. A Scott Walker win in Wisconsin would be equally good since his rise in the polls came only after an Obama visit. GOP wins in Maryland would be icing on the cake.
