President Barack Obama was fired up during a speech in Miami Thursday, telling voters that Donald Trump's acceptance of support from the alt-right and white supremacists portends an ominous future for the country if Trump wins the presidency.
"If you accept the support of Klan sympathizers before you are president, you will accept their support after you are president," Obama said, referring to the alt-right and white supremacist groups that have come out in support of Trump's candidacy.
Trump has denounced the KKK and KKK leaders, such as David Duke, saying he doesn't want their support. But earlier this year, it took Trump a few tries to come out with a forceful denunciation of Duke's support.
Obama went on an extended riff about why Trump is not fit to be commander-in-chief, saying his history of insulting minorities and women, stiffing workers and having too thin of skin to let satirical jokes roll off his back make him unqualified to lead.
Aside from saying Trump is unfit to be president, Obama also implored voters to get out and vote for Hillary Clinton, making a direct plea to younger voters, who some say may not show up in as high of numbers in 2016 as they did for Obama.
"This isn't a joke," Obama said, hitting his fists on his podium. "This isn't Survivor! This isn't The Bachelorette! This counts!"
He went on extended riffs about Republican obstructionism, which he blamed on GOP elected officials such as Sen. Marco Rubio, who is up for re-election in Florida.
Obama pointed out that Rubio had come out multiple times to say Trump was unfit to be president, but then backed his candidacy anyway.
"He tweeted, 'Friends don't let friends vote for con artists," Obama said, referring to Rubio. "So guess who just voted for Donald Trump a few days ago? Marco Rubio. Obviously he did not have good enough friends!"
Obama made the case to voters that it's not only the White House that matters when voters go to the polls, but also control of Congress.
He accused Republicans of being obstructionist, blocking Obama's agenda for the past eight years instead of being "for something."
Obama's comments come as polls have tightened, with Republican voters coming home to Trump after months of being wary of his candidacy.
After a fiery speech, he ended on the same message of hope that propelled him to two terms as president.
"I'm asking you to believe, not just in my ability to change things, one person's ability to change things, I'm not just asking you to believe in Hillary's ability to change things, I'm asking you to believe in your ability to change things," Obama said, telling voters that their votes matter.
"Choose hope," he added.
