There are currently 11 seats that the Democrats could conceivably
win next Tuesday. Looking at the races, at least four of the
Republican seats are definite goners -- New Mexico, Colorado,
Virginia, and Alaska -- with New Hampshire probably gone as well.
That leaves six races on the bubble, with Democrats and
Republicans each having the edge in three.
In Oregon and Minnesota, Democrats have to be favorites right
now, especially given Obama's likely victory margins in the two
states. I'd give Norm Coleman a better shot than Gordon Smith
just because there's always the possibility that Minnesotans
won't want to put comedian Al Franken in the Senate (though this
is the state that gave us Gov. Jesse Ventura). Trends have been
going against Elizabeth Dole and she isn't a great campaigner, so
Democrats have the edge in the North Carolina race as well, but
given that McCain will be more competitive in the state, let's
say she has a fighting chance.
That leaves us with three Republican seats -- Kentucky,
Mississippi, and Georgia -- that are more competitive than they
should be, but are likely to stay in GOP hands. McCain is
expected to win all three states comfortably, and I think that
the argument against unified Obama-Reid-Pelosi control of
government will have special resonance there. The most recent
polls show Roger Wicker taking a
commanding double-digit lead in Mississippi, while Mitch
McConnell continues to lead in Kentucky polls, albiet by a
narrower margin. In Georgia, though Democratic challenger Jim
Martin has made Saxby Chambliss sweat, Martin hasn't lead in a
public poll all year. A strong showing by Libertarian Allen
Buckley could keep Chambliss under 50 percent, thus triggering
the state's run-off rule. However, with the outcome of the Senate
already known by the time any run-off takes place, Chambliss can
explicitly make the "don't give Obama a blank check" argument in
a solid Republican state, and thus would likely prevail. (It's
true that some recent polls have shown the presidential race
getting close in the state, but Obama just released his
public schedule through Election Day and Georgia isn't on it,
suggesting to me that the campaign doesn't see a realistic
possibility of flipping it, and making it less likely that Martin
will gain the 50 percent needed to avert a run-off).
So, to sum up, the most likely outcome right now is that
Democrats gain eight seats, leaving Republicans with just 41
senators, which should be enough for an effectively
filibuster-proof majority given wobbly Republicans, but fall
short of an outright Democratic supermajority. The best hope for
Republicans right now -- barring a major upset -- is that they
hang on to at least two of the following three seats -- Oregon,
Minnesota, and/or North Carolina.
