"The looming liability right now for the Democrats is to go through a bloody, messy and expensive primary and then turn around with just six weeks to take on Scott Brown," said Mary Anne Marsh, a Democratic analyst in Boston. "So that's why Democrats have to think long and hard about who is running and trying to solidify behind someone who has the best shot at beating Scott Brown."
"Debates are the only opportunity voters have to see these candidate mano y mano," said Mary Anne Marsh, a Boston-based Democratic strategist. "You don't ever see them together other than in the debates. It is one of the only chances for voters to see how their candidate stacks up against the incumbent. In that respect, Mitt Romney has an invaluable opportunity."
