The early odds on favorite is Jeb for 2 reasons. 1st is he is extremely well connected to the beltway repubes. He’s gonna clean up on that money early and choke out the others. 2nd is he is perceived as being able to win FL easily. That is critical. There is almost no way for repubs to win white house without FL.
IMO Jeb Bush has zero chance to win the nomination. Look for him to fade after the first debate. He will not come out well agains’t the conservatives. They will all target him.
