Republican presidential candidate Donald Trump is spending the final day of the New Hampshire primary attacking a rival who is far behind him in the polls: former Florida Gov. Jeb Bush.

Speaking at a town hall event in Salem, New Hampshire, Trump went after Bush, calling him “a total stiff.”

He says, “Here’s a guy, honestly, if he weren’t in government…you wouldn’t hire him to do anything.”

He adds that Bush is “like a spoiled child” and “not a smart man” because he’s in favor of the common core education standards.

Later, in front of the Manchester Rotary Club at Fratello’s Italian Grille, Trump said Bush is “not smart enough to win” — and more.

For his part, Bush tweeted Monday that Trump is a “loser,” a “liar” and a “whiner.”
