Explinations and arguments:
The US 2 party system has the party canadates chosen at their respective party conventions. The state "Primaries" are actually about picking people to vote in your name at these conventions for the presidential nominee of that party. Just like that zaney electorial college stuff, these people are generally contracturally obligated to vote as their citizens expect. I'm not sure what would happen if there was a mass rebellion, if the votes would count even though the law was broken to do so, but that's a moot point. The point is that it's never been a states game, but a delegate game. This is why Ron Paul keeps insisting he'd win in the primary, and why escaped-from-a-sanitorium and the Grench stuck it out so long.
Enter the Romney. Romney is having a hard time pulling ahead from Obama. He has almost no lead amongst educated independants. Uncommited independants say that some things the Corporate canadate can be proven to have done would make a great deal of difference in choosing who to vote for, in a very negative way. In paticular issue is Bain and Taxes. Bain represents what is wrong with american investment banks. His saving grace is that is how a lot of people retire nowadays. He fails to understand though that most people who consider themselves "middle class" aren't in the income bracket he is targetting. He really fails to understand the true extent of "working poor" in this country or that the division between working poor and middle class is a small amount of money relative to what he earns. This disconnect creeps into all his discussion on growing the economy. He casually throws around plans that helps big business grow that do not offer hope for the people in the real middle class to have breathing room to fit their own plans for starting a business out there.
What Romney does have is rediculous amounts of money and a weak opponent. All he really has to do is prove he won't eat your babies and he's a shoe-in. With all his money this should be easy. The problem is he has no natural charisma. He fails every attempt at spinning things into positives for him. Romney is only ahead by the dislike for obama. The same people who dislike obama with Romney will dislike him with someone else. The Republicans say anyone but Obama. If they are serious about it, they should Replace Romney with someone who can get in dependants on his side.
Maybe the Mayor of Talkeetna, Ak should through his hat in the ring.
Seriously though. The Republican nomination isn't official until the convention. Romney can step down and Obama's expendatures to attack him would all be wasted, but the same isn't true the other way.
