Virginia
If Mark Warner runs, he's a tax hiking liberal. Tie him to the national Democrats and watch him sink.
Hawaii
Incumbent likely to retire. Run the Republican governor, if she isn't running for reelection; I'm not aware of any other good candidates.
West Virginia
If Byrd dies/retires, focus on guns and gay marriage, and maybe send Bush in there for some campaigning.
Rhode Island
Incumbency factor
New York
If Giuliani does not run, sit back, relax, and enjoy losing. If he does: Hillary = carpetbagger.
New Jersey
Incumbent may win gubernatorial election. A Dem would be appointed to fill the vacancy. That person would only be in office for a short period of time, so we don't have to worry about an incumbent. Just get a strong candidate.
Minnesota
Tim Pawlenty would be good, but he'll probably run for reelection. Anyway, run on the incumbent's lackluster Senate record, and maybe that closing Capitol Hill office thing.
California
If Feinstein runs against Arnold, we have no incumbent. Dems are still favored, of course. Run, I dunno, McClintock (sp?) maybe?
Tennessee
Tie opposition to national Democrats
Vermont
Hope the Dems run an opponent to split the vote; run a Republican governor or something
Mississippi
Lott may or may not serve another term. If he doesn't, attack the national Democrats.
Nebraska
This Nelson guy is good, so maybe get him to switch parties. Otherwise, just run a strong candidate, I guess. He's not very vulnerable except for being a Dem in a very Republican state.
Florida
The bad Nelson. Hope Jeb runs; he probably won't, in that case, I don't know who the best candidate would be.
Washington
One word: Rossi
Virginia: Too late, he already won rural aras
Rhode Island: He's down 20 points against one Democrat
New York:, and so was the guy who won that seat in 1964 and the guy who won that seat in 1970. Face it, it's the carpetbagger seat. Maybe you could run Keyes. Anyone but Guilani, and it's a landslide. Guilani will make it be a close race before he loses.
California: She's much more conservative than Boxer, who just won by 20 points, you can't beat her.
Vermont: Just look at the Vermont house races. Sanders wins landslides even when a Democrat runs.
Nebraska: He's quite conservative, but there's no reason for him to switch.
Washington: Gore campainging for her, and Rossi is toast.
