By the way, if you are pessimistic about the GOP's Senate candidates, and think they'll go 0-4 in the tossups (NV/AZ/GA/PA), you can get +900 right now on betting 49.
The big problem here is Laxalt. You're fading his likely victory, and even if he does get upset, then you have to fade all 3 other close races. I think you're much better off just betting on a 50-51 combo, or betting on just 50.
