And for all the enthusiasm the mention of Obama's name brings to the Democratic base, it is also certain to invoke a fierce reaction from the right.
Obama is expected to deliver the same message in Cleveland on Thursday where he will campaign for Richard Cordray, the Democratic nominee for OH governor, and other Democrats. "He is just capitalising on resentments that politicians have been fanning for years", he added before condemning the Republican party for "shielding" Trump from facing the consequences of his worst actions. "His speech next Friday will address the challenges and opportunities facing our country", Obama's communications director Katie Hill said in a statement. As the make up of California has shifted over the last several years, with its residents now a majority people of color, the margin by which Republicans have been achieving victory in Orange County has majorly decreased.
"It did not start with Donald Trump", he said.
"Some of you may think I am exaggerating when I say this election is more important than any I can remember in my lifetime", Obama said in a speech at the University of IL.
He told the audience they were coming of age at one of those moments.
Obama issued a scorching critique of President Donald Trump on Friday in a speech at the University of IL at Urbana-Champaign. Obama was "a lot lower key than yesterday's speech".
"I wish he had gone a little harder on Trump", said Lee Rice, 73, an electrician from Oakdale in California's central valley. I believe in you.
This gloves-off performance portends a return to Obama's "fired up and ready to go" campaign style and underscores his conviction that the midterm truly is "the most important election of his lifetime".
"They're undermining our alliances, cozying up to Russian Federation", he said. He will spend this Saturday in California stumping for seven congressional candidates at a Democratic Congressional Campaign Committee event and will head to OH next week to campaign for gubernatorial candidate Richard Cordray.
"For three cycles (2010, 2012, 2014) President Obama fired up Republicans like nobody", Rep. Steve Stivers, the head of the National Republican Congressional Committee, told reporters on Friday.
"I want to reach out to some Republicans, who kind of hearken back to the values of a guy named Abraham Lincoln, the first Republican president. He says 'people feel unsettled, people feel scared", and they're anxious about their children's future.
"It's not conservative, it sure isn't normal - it's radical", he said. We can march, we can rally, we can put signs up.
Saturday's rally was Obama's second campaign stop in a string of several planned appearances that Democrats hope will energize voters in an effort to flip 23 seats to take control of the House of Representatives.
