Scott Rasmussen writes in the Wall Street Journal:
Democrats face massive losses in tomorrow's midterm election. Based upon our generic ballot polling and an analysis of individual races, we project that Nancy Pelosi's party will likely lose 55 or more seats in the House, putting the GOP firmly in the majority. Republicans will also win at least 25 of the 37 Senate elections. While the most likely outcome is that Republicans end up with 48 or 49 Senate seats, Democrats will need to win close races in West Virginia, Washington and California to protect their majority.
There will also be a lot more Republican governors in office come January. It looks like six heartland states stretching from Pennsylvania to Iowa will trade a Democratic governor for a Republican one. A common theme in all the races is that white, working-class Democrats who tended to vote for Hillary Clinton over Barack Obama in 2008 are prepared to vote for Republicans.
But none of this means that Republicans are winning. The reality is that voters in 2010 are doing the same thing they did in 2006 and 2008: They are voting against the party in power.
Whole thing here.
