I’d vote for an orange juice can first.
First of all the voters decide the nominee, not a committee of GOPe.
Second, 2 or more conservatives staying in the race can not defeat one RINO candidate. Vote splitting will always kill the conservative candidates. Like in 2012 when Newt & Santorum & Cain and Bachmann were all running against ONE moderate from Massachusetts. There simply are not enough conservative voters in the country to anoint 2 or more conservatives over 1 RINO.
I know, reality sucks.
Third, if a repeat of 2012 happens in 2016, when 1 RINO defeated 2 more conservative candidates, are you OK to help Hillary get elected by staying home on election day? Do you really prefer Hillary over a RINO?
