It is an election year and the president isn't very popular right now. Just like some Republicans did in the 2006 elections with George W. Bush, some democrats are shying away from being seen with President Obama or even having it reported in the press that they were in the same city as the president. In Texas of all places, one would certainly not judge Wendy Davis if her schedule "coincidentally" happened to be full when President Obama made a trip to the Lone Star State.
