On why the republicans are poised to take the house

Almost every major non-democrat and even some democrat internal polls will tell you that a republican takeover of the House of representatives is on the cards. But hardly any of them say why. Well let me demystify. Here are some reasons why-

1. Anti Incumbency- No party can escape anti-incumbent sentiment of the populace. And in such times wherein a majority of Americans disagree with the people who represent them, it is but natural to see the democrat numbers dwindle as the party in power.
2. It's the economy stupid! - Again, I don't blame the democrats for this. It's not their fault that the American economy is in shambles. But the people of America are disgusted with the government and since democrats control both the law-making chambers, the people are disgusted with them too.
3. Enthusiasm, Enthusiasm and Enthusiasm - That's all you need to win an election. The republicans have done that very very very well. After the 2008 Political debacle for them, the republicans have managed to re-galvanize their voter base. 

These probably the three reasons why the republicans are poised to take the house. You see none of the three main reasons are faults of the democratic party but again politics is all about luck and the luck seems to have evaded the democrats.
