Former President Barack Obama is ramping up his involvement in politics ahead of November's elections. On Monday, he endorsed more than 200 Democrats running for offices ranging from local to national.

The endorsements include close races where his political cache could make a difference, veterans of his campaign and White House, and younger more diverse candidates. Last month, Obama endorsed 81 Democrats running in the 2018 elections. In a statement, Obama describes the candidates as "Americans who aren't just running against something, but for something."

Obama's moves come as he and former first lady Michelle Obama re-engage in public life. The former president has campaigned on behalf of several Democratic candidates, while Michelle Obama has been working to help lead a working group to help register new voters.

On Twitter Monday, he endorsed Kate Marshall for Lt. Governor, Aaron Ford for Attorney General and Nelson Araujo for Secretary of State. For House seats, he endorsed, Clint Koble, Melanie Scheible, Brittney Miller, Jason Frierson, Steve Yeager, Ozzie Fumo, Lesley Cohen, Michelle Gorelow and Sandra Jauregui. 

In August, he endorsed a total 81 candidates in the November midterms, including three Nevada candidates. 

On Twitter, he endorsed Rep. Jacky Rosen for Senate, Susie Lee for U.S. House, NV-3 and Steven Horsford for U.S. House, NV-4.

He went on to say: 

"I’m proud to endorse such a wide and impressive array of Democratic candidates – leaders as diverse, patriotic, and big-hearted as the America they’re running to represent."

"I’m confident that, together, they’ll strengthen this country we love by restoring opportunity, repairing our alliances and standing in the world, and upholding our fundamental commitment to justice, fairness, responsibility, and the rule of law. But first, they need our votes."

For Rosen specifically, Obama said: 

“I’m proud to endorse Jacky Rosen to be the next United States Senator from Nevada,” said Obama. “Jacky’s already proven herself a strong, thoughtful leader who can be trusted to do what’s right for hardworking Nevadans. She’s fought to protect the progress we’ve made on health care, to defend women’s reproductive rights, and to come up with smarter immigration policies that don’t tear families apart, but rather keep us all safe and strong. This November, the future of the Affordable Care Act and the Supreme Court are at stake – and our health care is more important than political games. That’s why I’m with Jacky Rosen. And that’s why I’m asking Nevadans to join her, and to help take back the Senate this November.”

“President Obama was a champion for progress who improved the lives of countless families across Nevada throughout his two terms in the White House,” said Rosen. “I’m honored to have earned President Obama’s endorsement, and I appreciate his strong support in my campaign for U.S. Senate as we work to flip this seat.”

Obama has kept a relatively low profile since leaving office last year. 

He also endorsed Steve Sisolak for Nevada governor. 

As for the Republican side, President Trump held a campaign-style in Las Vegas last month where he praised Senator Dean Heller and pushed Nevadans to get out and vote.

Trump also previously tweeted his endorsement for Adam Laxalt for governor. 

“I strongly endorse Adam Laxalt for Governor of Nevada. Adam is smart, works hard, and knows how to win. He will be a great Governor. Also, will fight hard to lower your taxes and is tough on crime!”

This year's midterm elections will happen on November 6th.
