Republicans fail to win in Delaware and Connecticut. They hold in New Hampshire and Missouri. Delaware, as many of us warned, was a missed opportunity and the downside of the Tea Party’s emphasis on ideological purity. It is also a lesson that establishment Republicans (in New Hampshire and Missouri) remain critical players in the party. For Sarah Palin’s critics, Christine O’Donnell’s loss will be Exhibit A in the indictment against her political judgment. That said, Rand Paul won, as will other Palin-endorsed candidates. It will be, I suspect, a mixed result for the Mama Grizzly.
