Update: Statement from Jessica Schultz, Ron Barber for Congress:
"Ron’s point last night was that the election on June 12 isn't about president Obama, or any other national figure--it's about who is going to do the best job fighting for middle class families in southern Arizona. While Ron does not agree with the President on everything, of course Ron has supported and will support President Obama in the election. His primary focus as a member of Congress will be standing up for Southern Arizonans."
