As much we enjoy the Bain attacks and the Colbert's Super Pac ads, we have to realize that the GOP still has wind behind their backs. Romney is attracting the angry voters who really believe that Romney has the best chance in beating Obama as seen in a piece by Alec McGillis;. MacGillis recognizes that the Romney is attracting the angriest supporters who tend to be the elderly and they vote reliably.
This explains why Romney's attacks border on contempt on Obama. I would also add that they are racist. In addition to the pent up anger, you have the lack of unity on the left. Hopefully, with the Bain attacks that this will galvanize the Democrats and Left especially in light of Romney's response to these attacks. The final reason that the election is for Romney to lose is the fact that the economy is still in a precarious state. The Europe is not helping the situation.
I don't think that we should sit on our butts and do nothing. I think we need to organize be it phonebanking or knocking on doors. I also we need to put out super pac ads to combat whatever bs that Romney will put out.
