I can only speak for myself but I have no current favorite or anyone that really excites me.
I will say based on his Governorship and what I've heard him say I do like Jeb Bush but I wouldn't vote for him based on his last name. Even if he is the best of his father and brother we don't need three people in a row coming from one family.
That is what gives me comfort about Hillary's chances in 16', the R's don't really have anyone that excites them. The divided soul of the party is going to make it hard for them to get behind a candidate. Things could change.
