Mitt Romney is filthy rich so he can self fund his campaign, has a large and experienced campaign staff, gets tons of media attention, and generally looks like he is going to be going into 2012 with a huge head start for the presidential nomination. However, he has tons of weaknesses that can be exploited. He passed Romney Care in Massachusetts, which is very similar to Obama care. He passed an assault weapons ban in Massachusetts. He has an overall liberal record and positions(until campaigning for president, of course...), but the previously mentioned issues I think would be great to rub in his face as much as possible.
Does everyone here remember how Giuliani had Ron Paul people protesting his events? There were Ron Paul signs and supporters everywhere he went for a while. I even remember a hilarious photo-shopped picture of him surrounded by the signs. I think Romney should get that same treatment. Everywhere he goes we should be there reminding everyone that:
"Mitt care=Obama care, say no to socialism"
"Mitt Romney thinks the 2nd amendment is about hunting"
"Go back to Massachusetts, and keep your socialism there where it belongs"
"The next Arlen Specter?"
