It is easy to fault Coulter for her flirtations with Governor Christie and discounts her observations. It is more difficult to apply the purge of Rinos in areas which are not absolutely clear. Given that that Senator Thad Cochran's ratings it is a no-brainer to primary him. That is not clear, however, in the case of Mike Enzi in Wyoming being challenged by Liz Cheney. I have voiced support for Cheney not out of enthusiastic support for her conservatism but for an assessment that she would be of higher visibility that Enzi who in my judgment has been sleepwalking through history. I've been taken to task by many FReepers, some of whom were from Wyoming and far more knowledgeable than I am about the lay of the land there, who point out that Enzi is sufficiently conservative. I accept that but I still question whether he is adequately leading.
On the whole, my feeling remains, execute a few of these Rinos to encourage the others.

I’ve had the same arguments with Enzi’s protectors. I agree with some of them that Liz Cheney is not the best opponent, but frankly, I’d prefer to replace Enzi with Cheney because he’s well on his way to becoming a Thad Cochran, and then replace Cheney in six years with someone more reliablly conservative.
As far as Enzi being sufficiently conservative, his record says otherwise. The ACU props him up but his votes speak for themselves.
Enzi (WY) - 2014 - 78% (Average) - 73% (Heritage) - 71% (CFG) - 92% (ACU) - 77% (FreedomWorks)
After all, he's been carrying a ton of water for GOPe.
I have no problem with your analysis on Enzi. In my view, he's been far too content to sit back and be one of the boys.
He's in his 3rd term, and what has he accomplished during the past 16 1/2 years? Like it or not, he has aided in the explosion of the debt during the last two presidencies.
