Does anyone have (or know where I can find)....

a concise tabulation of votes in all US House elections, Senate elections and the presidential election?* Preferably something in a spreadsheet (Excel) format.

The data I have found isn't anything I can download readily, and I'd like to do a few calculations on the numbers. I'm specifically interested in computing total Dem votes nationwide for House seats vs. to Rep votes, and also into breaking them down into certain regional comparisons. Would greatly appreciate any DU help with this!!


*I know not all of the votes are counted yet, but anything that's reasonably up-to-date will work.
