One of my biggest questions is how Indiana has went Republican every election since the 70's, up until Obama won the state. Indiana has many, many labor unions, from steel workers, UAW, farmers, and so on. But with Bush especially, the anti-union leanings seemed to not matter. The UAW sent out fliers criticizing Bush for not being pro-Union, but it didn't seem to matter. This last election, the UAW did put out TV ads promoting Obama, and basing an hypothetical situation in which McCain would be anti-union since he admitted he agrees with the President 90% of the time.
That article is interesting though, and it makes since. All I see from most Republicans is fear tactics, lies, and demonizing others. While the Democrats aren't much better, at least they aren't allied with big business.
