The 2016 Iowa caucuses...

...are only two years from next month. According to Scott Conroy, writing in RealClearPolitics, there are no fewer than nine Republicans considering a run (so far):

1. Arkansas Gov. Mike Huckabee
2. Pennsylvania Sen. Rick Santorum
3. Texas Sen. Ted Cruz
4. Kentucky Sen. Rand Paul
5. Wisconsin Gov. Scott Walker
6. Texas Gov. Rick Perry
7. Louisiana Gov. Bobby Jindal
8. Florida Sen. Marco Rubio
9. New Jersey Gov. Chris Christie

And I'll add two more:

10. Wisconsin Rep. Paul Ryan
11. Florida Gov. Jeb Bush

This could be a crowded field!
