Roberts has lifetime ACU of 86 and it went up to 89 against Obama
Roberts votes about like Thune
I bet the farm bills lower both scores
Vitter, Sessions and Steve King are the only people you can trust 100% on amnesty. They lose marks when they vote for state specific issues for their constituents like flood insurance and farm bill amendments.
One thing I think moderate Bill Cassidy did better politically, than Tom Cotton was vote for the farm bill. The bill was going to get passed, Cotton was going to win the GOP primary and Cotton still voted against it. Probably the only real issue Pryor could gain traction on .
