The biggest single reason why Governor Romney is the front runner is that he has had the overwhelming advantage in money spent and in “boots on the ground” running his campaign in states across the country.

Romney has outspent each of his rivals — and all of his rivals put together. His campaign organization has been operating for years, and it has put his name on the ballot everywhere, while neither Santorum nor Gingrich had a big enough organization to get on the ballot in an important state like Virginia.

In the general election, President Obama will have all the advantages against Romney that Romney currently has against his Republican rivals. Barack Obama will have boots on the ground everywhere — not just members of the Democratic Party organization but thousands of labor union members as well…

Rick Santorum, and especially Newt Gingrich, are fighters — and this election is going to be a fight to the finish, with the fate of this country in the balance. Mitt Romney has depended on massive character assassination advertising campaigns to undermine his rivals. That will not work against Barack Obama.
