I doubt it. If he sets up a party in the USA, it will not garner very many votes at all if they even run candidates. Obama will destroy the attempt, so it is more likely that his position stands a better chance to be part of the Republican platform. He does not have any expertise on US politics as you say.
The Dems and media will be behind any 3rd party that draws votes from conservatives. 1% will be the difference in close races . . .
