If the Democrats in MD are stupid enough to nominate Kweisi Mfume-and I don't think that they are, by any means-then I don't see how any Republican-unless Alan Keyes decides to abandon his newfound home in Illinois for a return engagemen-could possibly lose that (hypothetical) race.
I wouldn't be so quick to write off Kweisi in a general, especially in a state like MD. Many of us were WAY off in our calculation that nominating a radical nut with a scary name (who couldn't even win the nomination for a House seat when he ran previously) would lose in a landslide for a Senate seat to a Republican, and now that nut is the junior Senator from Illinois.
To ever speak of a Republican being unbeatable in a hypothetical statewide race in MD is ___. I simply cannot think of the word to use.
