At 9:00 tonight we get the VP debate. I don't think the debate itself moves people, but it is going to have an indirect effect because the media will set a narrative as a result.
If Biden has a great night the media narrative will be that he stopped the Republican momentum. If Ryan has a great night then there will be more media discussion of Republican momentum. For this reason, there is added pressure on both candidates.
What I hope happens is that there is substantive discussion of Romney's still unknown tax law changes, a discussion of voucherizing SS and Medicare, and a real debate about women's health issues. These are major agenda items and the American people should see the real difference between the candidates.
What I expect will happen is that Ryan will abandon his principles and pretend to be for some moderate/progressive policies. Biden will aggressively point out that he is totally at odds with past views and we continue to see the crazy evolution of the Romney/Ryan ticket to something that they are not.
