Being able to influence a presumptive Romney candidate, in VP pick and other affairs, rightward certainly can’t be accomplished by just sitting and storming “never, no way, should the heavens fall it is impossible, will I touch that (R) lever for the president in November.” If Romney or his campaign advisors are halfway rational people, they will say to quit worrying about those doing the storming. That’s the opposite of influence.
I got news for ya - they're not worried about conservatives at all, storming or otherwise.
