As Obama criticised US President Donald Trump's approach towards asylum seekers and the migrant caravan headed towards the US border via Mexico, a heckler cursed in response.
In Miami, Obama called it "gall" and "chutzpah"; in Atlanta, he labeled it "some kind of gumption" and "some kind of nerve".
"If this turnout mirrors the 2016 election for President, both Scott and DeSantis could win", the pollster said.
Hecklers interrupted Obama repeatedly during a rally in Miami on Friday.
"It's no surprise that (Democratic Sen.) Joe Donnelly is holding a rally this weekend with Barack H. Obama", he said, placing an emphasis on the "H", which stands for Hussein.More news: Yoga studio shooting: Class members tackled gunman who killed two women
Former President Barack Obama campaigns for Tallahassee Mayor Andrew Gillium (L), candidate for Florida governor, and Sen.
Trump will head to Montana and Florida today and Georgia and Tennessee on Sunday. Obama will return to the trail on Sunday, headlining rallies for Donnelly in Gary, Indiana, and in his hometown of Chicago for J.B. Pritzker, who is running for IL governor.
Evidence of this love and respect towards Obama gave was clearly visible during his address in support of senator Bill Nelson and gubernatorial candidate Andrew Gillum. "They're even taking our great troops away from their families for a political stunt", Obama said. "It's called promises made, promises kept".
"I'm the only one that tells you the facts", Trump said, after telling falsehoods about GOP efforts to take apart Obamacare and, with it, protection for people with pre-existing medical conditions.
"That's why I'm here", Trump said. "He's talking about how I should be nice to the fake news", Trump said.More news: Cormier defeats Lewis to retain heavyweight crown
Earlier in the day, Trump had responded to Obama's barrage by mocking the former president over what he described as a "very small crowd" in Miami.
The October economic data released Friday packed a wallop, finding that US employers added 250,000 jobs during the past month and unemployment remained at a five-decade low of 3.7 percent. More people entered the labor force and wages made their biggest gains since 2009.
Americans on Tuesday will elect lawmakers for all 435 seats in the House of Representatives, 35 seats in the 100-member Senate, 36 governors and dozens of state legislatures.
