No kidding. And with a campaign financed by Republicans, too.
Just that one defection answered the RATS prayers. Control of the floor in the Senate is a trump card. This cannot be overstated. Now Bush gets obstructed in the upper house of Congress at every turn.
That's one reason I am hesitant to be too eager for Miller to change parties now .... the same argument could be turned around and aimed at him since he ran as a Dem, in a campaign financed by Dems.
The other reason I think he serves a good purpose as a Dem is that as such, he can castigate his fellow Dems and not be accused of being a card-carrying member of the VRWC. Criticism from the Republicans is snickered at but criticism from a Dem has some sting to it.
