The Democrats need to kick them off the ballot for 2014 and run real Democrats.
SERIOUSLY. The minimum wage is a Democratic litmus test, or at least should be considered one. If you're a Democrat and you vote against raising it, you should just switch parties right now. You aren't a Democrat if you're against raising the minimum wage, period.
As much as I disagree with how they voted, think about it. Do we really want John Barrow's and Jim Matheson's seats to be open in a non-presidential election year?
I'm not saying we should primary these two in particular... but do we really have much to lose? It's not like we can win the House with such vicious GOP gerrymanders everywhere.
I don't expect the Democrats to retake the House any time soon, but losing two would just put us two behind. Their replacements would just vote party-line.
