This is reaching Hillary PUMA levels of nonsense. Romney will most likely pick a VP that satisfies movement conservatives, and more importantly he represents the right's best chance at stopping Obama, Obamacare, Dodd-Frank, etc.
Primary turnout may be low because of the lack of choices, and I'm not sure it demonstrates that republican turnout will be low in November
Dodd-Frank plays to the GOP establishment, of which Romney is the poster boy. He isn't winning support from evangelicals or tea partiers because he won't look to increase Wall St. regulations.
Obamacare = Romneycare. That direct parallel is easy as hell to draw and you can bet this fall a super PAC on Obama's behalf will carpet bomb this country with an eight figure add campaign to that effect. No one will trust Romney to get Obamacare repealed.
Roe V. Wade. Conservatives already have ZERO faith in Romney actually getting this tore down. He can't do anything to change it because he's been pro-choice publicly before.
Tea Partiers as a whole already see him as another big gub'mint deficit spender. Tea partiers are at heart a nutty group of libertarians. Most liberatirans think political gridlock is glorious. You really think they're going to put a big gov't. spender like Romney in with a rep. congress?
I'm not saying that Romney is somehow going to lose points to Obama on conservatives. But enthusiasm is tragically low for both sides. Obama's is this way because the other option hasn't been shoved in the far left's faces yet. Romney's is low because the far right just flat out doesn't like or trust him. How do you fix that?
The real relevance of this is how the far ends interact with their middle of the road friends. The moral right and small gov't. right will not phone bank for Romney. They won't go door to door for Romney. They won't preach to their co-workers about Romney. All they'll do is rail on Obama as he's getting us out of two wars and the economy is slowly rallying. Then they'll show up Nov. 4th and vote Romney while they hold their noses. That does nothing to win the middle. At the same time the left will push a real get out to vote movement and push to convert friends because Obama will look amazing in comparison to the alternative.
Meanwhile Obama will have a ton more money. His Super PACs will have more money (as they aren't burning it up through a primary). He'll have the power of the current office to minimize his real expenses and give him a larger soap box. He has a GOP controlled congress that makes his weak polling look stellar in comparison.
Most Americans identified with the Occupy Wall St. movement, they just thought the protesters themselves were a bunch of deadbeats. Romney is the exact kind of person the Occupy movement is attacking. That message coupled with slow economic growth will appeal strongly to the middle who will (like all elections) dictate the outcome.
