If the election's at all close, that's the same as voting for Half-his-age. You're just deceiving yourself that you voted to uphold principle or something.
Mitch declared war on Tea Party conservatives and said he would crush them thru out the country. I do not expect many TP Conservatives to be voting Mitch in Nov. It’s not smart to reward your enemy with your vote, not smart at all.
What's not smart at all is to keep Dingy Harry as Majority Leader so that he can help Obama poison the Supreme Court for a generation to come. That's why you should still vote for McConnell!
I left the GOP plantation during W’s second term. These days I mostly only vote for conservatives, I will make an exception if the candidate strongly opposes illegal immigration. So the only way to get my vote in a federal election is to be conservative or to campaign against amnesty for illegals. Happily here in Texas there are lots of good conservatives to vote for.
