Handing Donald Trump the authorities of the presidency would give him the power to turn some of his “twisted notions” into reality, President Barack Obama said Thursday.

Obama used the first half of a Florida double-header to urge a Miami crowd of supporters to make sure they vote for the Democratic presidential candidate Hillary Clinton and for Rep. Patrick Murphy, a Democrat seeking to oust GOP Sen. Marco Rubio from office.

“If we win Florida, we will win this election,” Obama roared toward the end of his remarks, which he acknowledged went beyond his staff’s plans. He urged the crowd to make sure their cousins and neighbors get to the polls, too.

“Tell them, ‘This is the moment when America makes a stand,’” he said. “Tell them, ‘This is the moment we reject cynicism.’”

As usual, Obama described Clinton, a former first lady, senator and secretary of State, as the most qualified candidate ever to seek the presidency. And he repeated his strong endorsement of Murphy on his third campaign visit to the state in as many weeks, saying Rubio shies away from tough votes, but Murphy fights on.
