Get rid of McCain at the convention and nominate a conservative. There does that help!
Problem. Cabinet positions are dead end roads to the White House. Too many ambitious names on that last. Some of those folks like Romney and Huckabee won’t be looking for cabinet jobs. others like U.S. Senators won’t want to give up their power in the Senate for a cabinet job. Cabinet jobs are good building blocks if you want to run for Gov , Sen or VP
later.
