If there is one safe prediction to be made about the ’08 elections, it is that the Republicans will throw everything they have into ending the Dems’ one-seat majority in the U.S. Senate. You can also bet the ranch that they will spend record amounts of money on attack ads that set a new standard of vicious innuendo and factual distortion. Expect one of the most grueling Senate campaigns ever.
In his RealClearPolitics article “Shifting Populations Will Impact ’08 Senate Races,” Reid Wilson says the hardest-fought Senate campaigns will probably be in Louisiana, where a GOP pick-up is most likely as a result of the Katrina-driven exodus of African Americans and in Colorado, where Dems are favored to add a seat, thanks to a rapid increase in Latinos and California progressives.
It’s early yet to be making numerical predictions. But so far Dems are in good shape to cope with the GOP onslaught to take back the Senate, according to Larry J. Sabato’s latest Crystal Ball round-up. Sabato shares his inside skinny on all the key races, and offers a cautiously optimistic prediction:

The Crystal Ball’s brutal bottom line is that Republicans will be playing much more defense than Democrats, and so the early betting line favors continued, perhaps enhanced, Democratic control of the Senate.

Seems a little conservative, considering the overall tilt of Sabato’s race by race rundown, but we’ll take it. For a more optimistic assessment of the Dems ’08 Senate chances, check out Senate 2008 Guru, who also provides a lot of insider detail.
Let’s be clear, however, that it’s going to take a lot of dough to offset the spending blitz the GOP willl unleash into the Senate campaign. So don’t put all your political contributions into the presidential race. Save a little for a close Senate race, so Dems can hold the line.
