A vote for Hillary Rodham Clinton will bring about a whole other type of global warming, Donald Trump cautioned Saturday.

“You want to have a mess of a country, you want to have nothing but problems, you want to have a country that goes to hell? You elect Hillary president, you have a country that goes to hell,” Trump howled at thousands of supporters at a campaign rally in Jacksonville, Fla.

Clinton enjoyed the best stretch of her campaign after performing strongly at the Democratic-primary debate last week and weathering criticism from House Republicans during an 11-hour hearing Thursday on her role in the Benghazi attacks.

But Trump trashed Clinton’s leadership skills and said he preferred to run against her.

“Based on that record I don’t know how you lose,” he said.

The bombastic billionaire also took shots at Republicans, slamming nearest rival Ben Carson for not being competent enough to be president.
