Sorry, US Senator Marco Rubio and US Senator Rand Paul and US Senator Ted Cruz.
Sorry, US Representative Paul Ryan, the former favorite son of Wisconsin Republicans.
But Wisconsin Governor Scott Walker says the next Republican nominee for president "should either be a former or current governor." After all that shutdown trouble, the party's candidate is going to have to be "somebody who's viewed as being exceptionally remote from Washington."
And sorry, New Jersey Governor Chris Christie. Scott Walker may have a kind word for you, but he says the GOP's 2016 candidate must be someone who has "taken on big reforms."
Indeed, sorry, any Republican who is not named "Scott Walker," but Scott Walker thinks the Republicans are going to need to turn to someone like, um, Scott Walker.
That was the takeaway from Walker's interviews as he launched the book that is supposed to launch his presidential run, Unintimidated: A Governor's Story and a Nation's Challenge.
Walker did not actually announce his candidacy on Sunday's edition of ABC's This Week. But as ABC's Jonathan Karl explained: "When Walker talks about the kind of candidate Republicans should nominate in 2016, it sounds more than a little like he is talking about himself."
The Wisconsin governor did nothing to stifle speculation.
Despite repeated prompting from ABC's Karl, Walker refused to commit to serve out the second gubernatorial term that he is expected to seek in 2014 -- presumably on the bold assumption that said term could interfere with a move to the White House in 2017.
