My opinions are:
1. Hillary Clinton will be his hardest challenge.
2. Don’t laugh, I think Sarah Palin in 2 years will gain in popularity, especially if she has Marco Rubio as a Latino running mate.
3. A vast number of very qualified persons such as Mike Pence, Paul Ryan, Senator Demint, Senator Lacey, Senator from Texas and a number of yet known names.
Who do you pick?
