Joe Biden just defended Obama's plan to raise taxes on people who make over $250,000 a year. Sarah Palin responded that this meant raising taxes on small businesses. This is the kind of thing that you get in trouble with if you don't understand your own talking points. She was supposed to say that tax increases would effect small business owners, but she either messed that up or just doesn't quite get the distinction. Either way, it's very revealing. Biden managed to subtly highlight the difference in his response when he pointed out that most small business owners don't make more than $250,000 a year -- it may have just been in my head but I thought he emphasized the word owners heavily.
