They already did that by who they endorsed in last year's primary. The line-up of who endorsed Romney before Newt and Rick dropped out lines up closely with those who are denouncing Cruz (not to mention those who backed the NSA spying). Guys like King, Coburn, McCain... There is no mystery about who the RINOs are in most cases.
It’s not just the Rhino’s who need to go Jedi.......this entire Healthcare issue is smoking out who is ‘for the American people’ and who is not. That was the major point of Cruz’s stand.....that ‘Republicans’ aren’t doing the “peoples” work they hired them for.
The Old guard needs to go as well....not just Rhino’s.
