A gross over reaction in my opinion. To read the myriad articles you would think Rove had denounced Sarah Palin, Jim DeMint and the entire Tea Party movement as unpatriotic and un-American. To read the reactions you would also believe that he had caused O’Donnell’s defeat.
He may yet.
I haven't yet tried to unravel the thing but Rove claims she carries some unacceptable baggage while she replies she's traveling light. Have to let the dust settle a bit to see what's there.
