If election-fever is making you sweat right now, try No Left Turns for Ohio analysis (including Dems trying to suppress Republican votes; won't hear about that on CNN!), The Corner for those crucial every-3-seconds updates, and the Townhall C-Log for colorful poll experiences.
If you're still undecided (ha!), check InsiderOnline.org's Federalism, Governing and Elections section for information on the candidates' positions and more mouthing off about this nearly-over election.
Daschle v. Thune also has... Daschle v. Thune updates, and the Locker Room has the Burr v. Bowles NC Senate race handled. More blogs on individual races as I find them. In the meantime, take a deep breath.
