"In two months we have the chance to restore some semblance of sanity to our politics", he said in a speech at the University of IL at Urbana-Champaign.
"You've got to do more than retweet a hashtag, you've got to vote", he said.
Even as he has largely remained out of the spotlight, Obama made clear he's paid close attention to the steady stream of headlines chronicling the Trump administration and said the news is a reminder of what's at stake in the November midterm elections.
Obama, who has kept a relatively low profile since leaving office, took a step back into the political realm on Friday when he critiqued Trump and Republicans. Anti-communism used to be the rallying cry of the conservative, pro-capitalism movement in America and yet now they seem perfectly comfortable with the leftover Soviet spy running Russian Federation.
President Donald Trump has been a busy boy today, calling on Attorney General Jeff Sessions to investigate the author of this week's op-ed assuring Americans there is resistance inside the Trump administration.
"Demagogues promise simple fixes for big problems", Obama said, swiping at Trump. When most Republican elites who are skeptical of Trump use the word "normal", they have in mind the policy agenda supported by Paul Ryan and Mitch McConnell.
An Obama office official said before the speech that they could not say whether the former president would mention Trump directly in IL but added that "regardless of whether he mentions him by name, it will be very clear who he is talking about". "If I was the Republicans, I would be very nervous about this". He doesn't have a strong record of helping his party win when his own name isn't on the ballot and Democrats suffered significant losses during both Obama midterms in 2010 and 2014.
He called for "a restoration of honesty and decency and lawfulness in our government".
"If you thought that elections don't matter, I hope these last two years have corrected that impression", he said. "A politics of fear and resentment and retrenchment takes hold". Obama is likely to be less helpful in some of the most competitive Senate races playing out in states Trump won.
"In 2016, voters rejected President Obama's policies and his dismissiveness towards half the country".
'It shouldn't be Democratic or Republican to say we don't target groups of people on how they look like. Okay? You didn't go out to vote.
ABC News reported that "Trump told U.S. Ambassador to Germany Richard Grenell to make Palij's deportation his number one priority when he got to Berlin".
Obama was editing his first public speech of the 2018 midterms on the plane, an aide to the former president tells CNN, scribbling notes and crossing out lines on a printed copy.
