There are many paths to the presidency, most of them a standard climb from one elected office to the next.
A whole passel of lawmakers have cycled their way through a governorship or the U.S. Senate en route to the White House. Others arrived with less buttoned-down backgrounds. There have been war heroes, a former haberdasher, a onetime movie actor.
And then, of course, there is the current occupant whose resume — real estate developer, beauty pageant promoter, conspiracy monger, reality TV celebrity — comprises a category all its own.
