This was a district that had a Democratic Congressmen for over 80 years. It is heavily Democratic (3:1 ratio), working class, pro-union, and has a high concentration of Jewish people, all groups that tend towards the Democratic candidate.
It is easy to simply say that this was a rebuke of Obama's policies and move on.
Look deeper though and there could be real trouble for Obama.
-A pro-union electorate. The significance of this is being downplayed by the left because the unions did not get heavily involved in the race.
First, that is a problem in itself. There has been rumors that the unions will not be as heavily involved in the next national election in 2012. Obviously they will support Obama and work for him. Word though is that they may choose instead to focus on local races and campaign for their cause on their own.
Unions accounted for over $400 million in support last election, if that is decreased that could be a concern for Obama.
Second, so what if the union were not active? Are we to believe that union members are so stupid that they are unable to decide how to vote if the union apparatus is not telling them?
-Jewish voters. Some of their vote was possibly diminished because socially conservative orthodox Jews were unhappy with Democrat Weprin for voting for Gay Marriage. With that said, at the end of the day few people decide their vote on one single social issue.
I think this may be a significant danger sign for Obama. The Jewish vote is a pretty reliable one for Democrats. Obama has spent his Presidency bowing to countries that want to destroy Israel and at the same time pissing all over Israel. To me it seems almost inevitable that he will lose ground on the Jewish vote.
This election was made to be about Obama. An upstart Republican candidate with no experience beat a seasoned Democrat in a district that is 3:1 Democrats over Republicans by 8 points. Pay attention to who you vote for in the Primary election folks, this election is ours to lose.
