While Mike Pence is my first choice if he runs, I can vote for Walker. I can vote for Cruz. I will not participate in some BS circular firing squad against the good, but not perfect, people running. When we get involved in purity tests, we lose to the democrats. We also get stuck with our worst choices for nominee like in 2008 and 2012. McCain? Romney?
The problem in 2012 is that everyone savagely attacked anyone conservative running to clear the field for someone who wasn't even running (Sarah Palin). The same people then turned on Palin for "betraying" them because she didn't run.
Right now, there is one guy to attack. Jeb Bush.
Pence is good because he hasn’t finished his term. Walker not so much.
