The DOW was in the 14000 range in Oct 2008 when it was clear Obama was the Democratic nominee. The media was clearly biased and McCain didn't have much of a chance. The year was closing and the street saw what was coming. Had nothing to do with GWB. I think you have your dates wrong. But I could be wrong to and I'm sure you will correct me if I am.
well Obama was the front runner and the likely nominee and likely winner which all turned out to be true. The dems already took control of congress in 2006. Things started going down hill before he was actually elected. http://www.google.com/finance?client=ob&q=INDEXDJX:DJI
