Because Hope & Change:

Weary of waiting for an economic recovery worth its name, a frustrated American public has sent Barack Obama’s job approval rating to a career low – with a majority in the latest ABC News/Washington Post poll favoring a Republican Congress to act as a check on his policies.

Registered voters by 53-39 percent in the national survey say they’d rather see the Republicans in control of Congress as a counterbalance to Obama’s policies than a Democratic-led Congress to help support him. It was similar in fall 2010, when the Republicans took control of the House of Representatives and gained six Senate seats.

Of course, Republicans will try as hard as they can to blow that lead. That begs the question: Why are statist Republicans pushing immigration reform? That just hands Democrats a larger share of the electorate.
