RealClearPolitics.com is NOT a lib-leaning site. They were very accurate on their state-by-state election forecast for the presidential election in 2004 and they were the only site I saw that projected the surprising Republican showing in the 2002 mid-term elections. I also remember that in 2002 they predicted that Zogby was going to be really embarrassed the day after the election, which of course turned out to be true. He was still apologizing a month later.
By the way everyone, according to RealClearPolitics the Democrats are NOT in good shape to pick up the Senate, just in case any of you are still wondering if they're shivving for the libs.
