Isaac Wood takes an early look at the 2012 House races:
Whatever the result of the presidential race, there is one constant that should be sobering for Democrats chomping at the bit to recapture the House majority. Over the 13 presidential elections of the past 50 years, only twice has either party registered a net gain of 25 or more House seats, the threshold Democrats must cross to regain control of the chamber. At least for the past half-century, the true wave elections have come in midterm years (2010, 2006, 1994, 1974, 1966) while the presidential years have seen calmer seas.
