Polling Suggests Tea Party Could Lose House Independent voters gave the tea party control of the U.S. House in 2010. Now 68 percent of independents disapprove of House Republicans. We find Democrats with a 7 point lead on the generic Congressional ballot this week at 47-40. After getting demolished with independent voters last year, they now hold a slight 39-36 advantage with them. And in another contrast to 2010 Democratic voters are actually slightly more unified than Republicans, with 83 percent committed to supporting the party’s Congressional candidates compared to 80 percent in line with theirs.
