Ohio got a lot of press in 2004 because Democrats made unfounded claims of voter fraud. What we forget is that Bush's narrow loss in PA was even closer than Kerry's loss in OH.
So let's look at PA, which could cost Democrats more congressional seats than any other state in 2010. Toomey leads Specter by a healthy margin. Corbett also leads statewide. Corbett's election would really signal a warning sign to the supporters of a government healthcare takeover.
What we should find is that a Republican Attorney General who promotes suing the federal government to BLOCK implementation of Obamacare is highly favorable and popular in a blue state... and the favorite to become governor. Corbett can ride opposition to Obamacare to victory every bit as much as Scott Brown rode to victory by openly declaring that I WILL BE THE 41st vote AGAINST Obamacre!!
Come to think of it, is there any state in the Big Ten in which Republicans can't win the governor seat? Democrats' tax-and-spend schemes have failed. And Democrats' cap-and-tax schemes would cause even more damage to the "Rust Belt". For that matter, it was Democrats' slavishness to unions and bureaucrats and environmental extremists and high taxes and oppressive government regulation that turned the Great Lakes into the great Rust Belt.
But Pennsylvania should be a great test case.
