Who from the republicans has the best chance of beating hillary?

gulianni is probably most likely to beat her but RON PAUL IS THE BEST!!!!!!!!this guy has the best views of any candidate i have ever heard...seriously, he's so good it blows my mind....he wants to pull out of all international institutions, stop fed income tax, give the states more power(they decide on gay marriage), reverse roe v. wade(end abortion), pull out of iraq, he dislikes the liberal gun control policy, he wants to end the war on drugs, legalize med. marijuana and let states handle pot however they want...GREAT!
