The Republicans' confused assortment of announced presidential candidates— as well as unannounced candidates and distant possibilities of candidates— seems to be clarifying somewhat. The withdrawal of Donald Trump and Mike Huckabee, as well as the withdrawal of much of Newt Gingrich's staff, seems like a much-needed weeding-out process.
Although Mitt Romney has been leading in the polls, his lead over other potential rivals has been slim. Being a "front-runner" this far ahead of next year's nominating convention would not mean much, even if Governor Romney's lead and his support were much bigger than they are.
The albatross around Romney's neck is the RomneyCare medical plan that he signed into law in Massachusetts. His refusal to repudiate RomneyCare means that, as a presidential candidate, he would forfeit one of the strongest argument against Barack Obama, who has ObamaCare as his albatross.
