What should be Romney post-conventions strategy?

[SPC]

Having a natural affinity for the underdog, I'd like to think about what Romney should do to win. However, the problem seems to be that the main obstacle preventing Romney from doing that is Romney himself. Even without all of his gaffes, he is simply a terrible candidate for virtually every swing state.

The only idea I can think of that would give him a Hail Mary would be to repudiate the Ryan budget proposal and instead call for dramatic cuts in military spending to make incremental cuts to social spending more palatable. Obama would be unable to successfully attack him on this for much the same reason Romney has been unable to attack Obama on foreign policy. Obama could attack Romney for flip-flopping, but given Romney's reputation I hardly think this would do any marginal damage. Of course, Romney's a hyper-militarist so this would never happen.
