Three-time candidate for president Ron Paul said Wednesday he does not like any of the remaining GOP candidates in the 2016 race, and would not support Donald Trump if he were to win the Republican nomination.

Trump has been able to tap into the anger and fear of a large "minority" of voters, Paul told CNBC's "Squawk Box." He said the billionaire businessman acts like he has all the answers but "zero" realistic solutions to the problems facing the nation.
