Background (Part 1)
2008 Presidential Election
The 2008 Presidential election effectively began when Illinois Senator Barack Obama announced he wouldn't be running for president. This left the field wide open, with Senator and former First Lady Hillary Clinton becoming the effective front-runner by the summer of 2007. On the Republican side, Rudy Giuliani was widely seen as the front-runner, and a Clinton-Giuliani election was seen as the most likely matchup. However, when Iowa came, Clinton pulled off a narrower-than-expected victory against Joe Biden, winning by only two-fifths of a percentage point, while for the Republicans, Giuliani took only 3% of the vote. After winning the New Hampshire primary by 18 points, Biden tied up most national polls and kept the delegate race close with Clinton. By this point, Giuliani and Mitt Romney dropped out, leaving John McCain's only legitimate opposition as Mike Huckabee, who dropped out weeks later. Former Senator John Edwards won 4 primary states, but dropped out after getting only 168 delegates on Super Tuesday, putting him far behind Clinton and Biden. By the time the final June primaries rolled around, nobody had a majority of delegates, but superdelegates and the endorsement of Edwards put Biden over the top. McCain chose Alaska governor Sarah Palin as his running mate, while Biden chose Senator Charles Schumer. Throughout the campaign, Biden took large leads at points, but overall the polling showed an extremely tight race. In fact, the polling average for every poll from July to Election Day only showed Biden with a 3-point advantage, but at certain points Biden led by as much as 16 points. Despite having a slim polling deficit on the eve of Election Day, Biden ended up winning a comfortable victory in the general election, with the Biden/Schumer ticket taking 319 electoral votes to McCain/Palin's 219, and he won a slim majority in the popular vote, taking 50.2 percent to McCain's 47.1 percent.
There is no way Sherrod Brown loses reelection.
Yeah, I realize now that in a year that the Democrats won that many seats, the Republicans couldn't win unless they ran Kasich (which I think is unlikely). I fixed it but kept the Senate balance at 51-49 by removing the Democrats' defeat of Jeff Flake.
