Newt needs to be in Congress. He proved he couldn't handle Clinton in the '95 government-shutdown coup. He proved he couldn't handle the Speaker's job, which also shackled him as an advocate of conservativism.
He needs to be in Congressional leadership, preferably the House -- he needs to be Majority Leader in the House or Senate, House better than Senate because of the clubbiness of the latter which would cramp Newt's style.
Newt's a cheerleader, and we need a cheerleader in a cheerleader's job. We also need him as a conservative sitting in the decisionmaking circles of Congress. He could do a good job in the Bully Pulpit, but the MSM will never let him get there -- they singled him out for destruction immediately after the 1994 elections and went to work on him (I saved that "Man of the Year" hate-photo TIME put on their cover), and they basically hung a frame around him. He'd never get to the White House.
