President Trump’s campaign team is increasingly grim about a repeat performance of keeping Michigan red in the traditionally blue Rust Belt state.

After a midterm election that decimated the ranks of Michigan Republicans, Trump’s campaign is looking to other battlegrounds he lost last time — such as Minnesota and New Hampshire — that they see as more promising.

The assessment illustrates how Trump’s support in the Rust Belt states that propelled him to the presidency has softened, jeopardizing his prospects for a second term.

“It’ll be tough,” said Greg McNeilly, a veteran GOP strategist in Michigan.

Though the president overcame tough odds in 2016, winning the state by 10,704 votes, or less than 1 point, McNeilly expects Democratic turnout to be stronger in 2020.

“Trump is the underdog,” he said.

Trump’s biggest challenge in the state — and the main source of his campaign’s concern — is Wayne County, a liberal population center encompassing the Detroit metro area.

Hillary Clinton won the county last time by just 289,000 votes; by contrast, Obama carried it by 382,000 votes four years earlier.

Even partially closing that gap would put Democrats, who have lost the state only once since 1988, in the driver’s seat.

Trump allies say Clinton took the state for granted and failed to mobilize voters in heavily black Detroit — a mistake Democrats aren’t likely to make again.

As Trump worries about losing 16 electoral votes in Michigan, the Progressive organization Way to Win announced plans to invest $50 million to help the Democratic Party in the Sun Belt.

The group’s blueprintdetails a strategy to help Democrats in Georgia, Arizona, Texas, Florida, Virginia and North Carolina, where the party hopes to make inroads with people of color, women and young people.

“It’s preparing to win not just in 2020, but to build power in the long term,” Tory Gavito, president of Way to Win, which was founded after President Donald Trump’s 2016 win, told AP.

Way to Win previously spent $22 million during the 2018 midterm season.

The group told AP that President Trump’s 2020 strategy, which focuses on his base, offers opportunities for Democrats to make inroads in the states they have often lost.

“It’s a threat,” Gavito said. “2020 is a race to drive up the most new voters possible. Our job is driving forward the new electorate in the South and Southwest.”

Progressives also say that shifting population compositions in Sun Belt states means some Republican-dominated states may be in play.

If Trump loses Michigan, it wouldn’t necessarily cut off his path to reelection.

Trump won 304 electoral votes in 2016, meaning he still has a cushion keeping him above the 270 threshold.

But if his problems in the state bleed over to Wisconsin and Pennsylvania, which collectively account for 30 electoral votes, it could well doom his chances, even before you discuss the emerging purple Sunbelt.
