Close races breaking the Democrats' way?

There's a lot of buzz about the Democratic candidates in close races this year. This Boston Globe article talsk extensively about some of the races to watch:

Control of the Senate could be critical for the next president. If Democrat John F. Kerry wins but faces a GOP-controlled Congress, it is unlikely he will be able to pass major domestic initiatives. If Bush wins reelection but is hamstrung by a Democratic-controlled Senate, he will have a more difficult time getting his judicial nominations approved.

In Oklahoma, Democrat Brad Carson's strong showing in early opinion polls could mean a gain for the Democrats and a new Native American senator. In Colorado's race to replace Republican Senator Ben Nighthorse Campbell, Democrat Ken Salazar, leading in polls, could become the first Latino in the Senate in a quarter-century. Alaska, once a guaranteed Republican stronghold, now appears in play, with incumbent Republican Lisa Murkowski -- who replaced her father, Frank, when he became governor -- trailing slightly in the polls.

And a contentious Republican primary in Pennsylvania could offer Democrats an opportunity there if challenger Pat Toomey upsets veteran moderate Republican Senator Arlen Specter April 27.

Barack Obama in Illinois is not mentioned in the article because his race, as of the latest polls - isn't even close. In the good way :)

What I think we need to do is focus on a single candidate each month and show them our Dean Nation love. Arguably, the Senate is more in play than the House, but we can support candidates for either house. Who should Dean Nation support for April? Leave your suggestions in the open thread (and I've linked the nomination thread at left so it won't scroll away). We will choose our candidate for April at the end of the week based on the feedback. Let's flex our muscle again!
