Weekly Standard's Stephen Hayes' Republican countdown

There's a great deal of analysis and explanation for these choices at the site, so you should probably read the whole thing.

I've just boiled them down to an ET-style countdown list just because I found some of the placements interesting and you might, too.

So in reverse order—from least likely to most likely—here’s a look at the prospective GOP nominees.

19. Donald Trump

18. Paul Ryan

17 & 16. George Pataki/Bob Ehrlich

15 & 14. Lindsey Graham/John Bolton

13. Carly Fiorina

12. Rick Santorum

11. Ben Carson

10. Mike Huckabee

9. Bobby Jindal

8. Rand Paul

7. Chris Christie

6. John Kasich

5. Rick Perry

4. Ted Cruz

3. Jeb Bush

For the final two: It’s a coin toss. If I were betting on the likely GOP nominee today, I’d put the same amount on [Scott] Walker and [Marco] Rubio (with a chunk on Jeb, too).
