THE MYSTERY CANDIDATE. The blogosphere has been consumed today with the unnamed GOP senatorial candidate who lit into George W. Bush at a reporter's breakfast. The whole situation was a bit weird -- the cloaked complainer was frustrated at the GOP's weakness and Bush's unpopularity, so it's not clear why he didn't rip off the mask and try to carve out some public independence. In any case, ABC News confirms that the man behind the mask is Maryland's Michael Steele. I wonder how the rest of the GOP feels about him publicly blasting the party to reporters -- feeding the Bush-is-unpopular and GOP-is-doomed narratives -- while hiding behind assured anonymity.
