I am sick and tired of analysis that whines about redistricting by Republicans. The winning party gets to do that. It then becomes an advantage of incumbency which is no different than the advantages that a presidential incumbent has. Besides, Republicans have gained at other levels of govt, not just in the national govt. Factor these points in with the fraud that occurred in the last presidential election where there were more voters than registered in certain districts and those live videos by undercover people showing Obama voters planning to vote in two places. This even happened in southern NH where I have family. I am not saying it means Mitt won, I do think it shows that Obama's win was much, much closer—at the very least which is more reflective of polls showing a dead heat. This is typical Chicago politics.
“Experience should teach us to be most on our guard to protect liberty when the Government’s purposes are beneficent. Men born to freedom are naturally alert to repel invasion of their liberty by evil-minded rulers. The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding.” — James Madison
