Romney is wearing his opponents down, one at a time. Giuliani will be gone after tomorrow.
Romney is not wearing his opponents down, he is beating them with money. This prooves that a nomination can be bought.
He's not wearing Ron Paul down. In fact, I guarantee you Mitt is probably discouraged that Paul is still in the race.
Because for all of Mitt's money, he doesn't have dedicated grassroots supporters who are all out there spending their own time and money to help Paul get elected.
And God help Romney if it's just him and Paul debating.
