The prices were on the way down before the crash...and the crash was principally a financial crisis brought on by the Housing crash which, IMHO, was engineered by the democrats themselves.
Obama tied to the Economic Crisishttp://www.jeffhead.com/http://www.jeffhead.com//obama/communityorgan.htm
Watch the video linked there, “Burning down the House,”...it explains the crash very well.
I saw it many times (it was better with the orginal music) but it left out GWBs CRA type ‘get minorities with bad credit home loans’ initiatives and speeches from 2002 to about 2004.
If CRA was a major cause of that financial crisis then it doesnt absolve GWB’s finger-prints all over it with Democrats.
Oil prices pretty much mirrored the DJIA in 2008. Both had a dip in mid summer and then took a major dive in October.,
I will have to do some screenshots that period and upload them to photobucket to show how remarkably similar they were.
I don't recommend doing that again to lower gas prices.
