The second presidential debate will be held tonight at 9 pm ET. In the two weeks since the last debate, Obama has gained a slight lead over McCain in the polls.Tonight the candidates will be debating in a town-hall style; answering questions from the audience and from viewers over the internet. This generally means a wider range of topics, but less in-depth answers. Questions are also expected to focus more on the current economic situation than the previous debate.So are you going to watch the debate? How did your candidate do? Tell us by voting and joining in the discussion!
