Many Republican activists say they want a governor to be their next presidential nominee. The buzz centers on New Jersey's Chris Christie for now.
But Wisconsin Gov. Scott Walker is trying to climb into the 2016 conversation.
Some GOP insiders say he's a can-do governor with Christie's good qualities and few of Christie's downsides.
If Walker wins re-election next year, he can join Christie as a two-term Republican governor who thrives in a Democratic-leaning state.
Walker's supporters say his more conservative stances on several issues would help him in GOP primaries. And they say Walker's calm Midwestern demeanor will play better in many places than will Christie's penchant for bombast and confrontation.
But Walker is untested on the national stage and not well-known outside Wisconsin.
