Former President Donald Trump knocked New Hampshire‘s open primary system and claimed Democrats would show up in droves for former U.N. Ambassador Nikki Haley. The comments came days before the state’s first-in-the-nation primary contest that will serve as a precursor to the rest of the Republican presidential nomination race.

Trump said in an interview with Fox News host Sean Hannity on Thursday that Democrats will take advantage of the open primary and will likely vote for Haley. Hannity said thousands of Democrats have switched their affiliations to Republican or undeclared to vote in the primary on Jan. 23.
