Democrats are going to have to split the Republican vote to win in 2012. They’ll keep pushing Mitt as a financial conservative and try to woo over the country club Republicans..
The Left will work to depress the GOP vote (w/ a Romney nomination) which will inhibit 2012 GOP voter TURN OUT (which they KNOW is softening for their team) and set up as many places where fraudulent voting will help (and they're fighting the voter ID bills passed in TX, GA and WI).
