Obama's central mistake in the last debate was that he mistook political theater for a rational policy discussion. He needs to be smart, but snappy when getting his points across. Also, I really hope that he points out again that Romney's health care plan does not cover those with pre-existing conditions. That was a blatant attempt by Romney to mislead viewers last week. His policy preserves the current status quo. Obama pointed this out by calmly explaining why what Romney said isn't so, but he needs to be less wonk-ish and more direct.
And Obama must remind voters that, not only does Romney want to force women to remain pregnant against their will, he picked a VP nominee who would like to force raped women to remain pregnant, even if they are teenagers and their rapists are family members. I hate typing this stuff, I don't like controversy, but it's the truth.
Let's hope for a good and honest debate tonight!
