WASHINGTON — Senate Majority Leader Mitch McConnell declined Sunday to say whether presumptive Republican nominee Donald Trump is qualified to be president.

"I think there's no question that he's made a number of mistakes over the last few weeks," the Republican leader said on ABC's This Week. "I think they're beginning to right the ship. It's a long time until November. And the burden, obviously, will be on him to convince people that he can handle this job.''

Pressed to directly address Trump's qualifications, McConnell said: "Look, I'll leave that to the American people to decide.

"You know, he won the Republican nomination fair and square,'' the Kentucky senator said. "He got more votes than anybody else against a whole lot of well qualified candidates. And so our primary voters have made their decision as to who they want to be the nominee. The American people will be able to make that decision in the fall.''

McConnell's less-than-enthusiastic assessment comes as new polls show presumptive Democratic nominee Hillary Clinton holding solid leads over the New York real estate magnate.

A Washington Post-ABC News poll shows the former secretary of State with a 51%-39% lead, while a NBC News-Wall Street Journal poll had Clinton leading by a single-digit margin, 46%-41%.
