I don’t think what Obama does matters anymore. Voters are watching Romney, giving him the benefit of the doubt, and hoping he can close the deal.
I think you are right. In listening to “undecideds” interviewed after prior debates, one negative for Romney is lack of specificity. If he can get out from under the “you lied about your tax plan for the past 18 months” meme and can show SOME specificity other than “closing loopholes”, I think he can close the deal with a great number of undecideds. The folks know Obama has failed so far and Romney is showing he is not the villain portrayed by the left.
I agree. People disenchanted with Obama are looking at Romney and asking themselves "How comfortable would I be with this guy being President". Romney just needs to maintain a presidential attitude on stage.
If Obama has a public psychotic episode on national TV, then that's just a bonus.
