30% of conservatives most likely will not vote for Romney if Rubio is vice pick. If that is the case, most will write in Ron Paul.
RNC needs to get its head screwed on straight. This will be the last major two-party election in our country if Republicans mess this one up. A lot of people are holding back campaign money and support to see how this ticket pans out this summer.
Rubio can become one of America's best longtime Senators. We need one. A 'Kennedy' of the conservative party.
