fwiw
The guy that has been sneaking up the odds board is JD Vance.
In the past two weeks or so he has gone from 10th choice to 4th choice in the betting.
Plus, his wiki page has been cleaned up a little bit recently.
Currently:
Scott 4/1
Gabbard 8/1
Noem 12/1
Vance 15/1
A couple of weeks ago, I put JD on the top of my list.
