If the Senate tips to the Republicans this November and the House remains majority Republican, if they do not indict him in the House (impeach) and try him in the Senate and get 100% Republican support in both houses, then there is no point in voting for any Republican come 2016. No point at all.
What then do you suggest?
The alternative to voting Republican is war in the streets
Remember that conviction in the Senate is not by just simple majority vote. It has to be two-thirds. Even with the most optimistic assessment of GOP chances to take the Senate in 2014, they won’t even be close to the number required. And, you know the Dems will vote in lockstep against conviction.
