At least 20 presidential candidates will descend on Michigan this week as they prepare for and participate in the second round of Democratic presidential debates at Detroit’s Fox Theatre on Tuesday and Wednesday.

Since most tickets have been reserved for party and campaign officials and guests, with only a small handful offered to the public in a raffle, several contenders are taking the opportunity to campaign in other parts of Michigan, as well.

Particular pressure has been put on candidates to visit Flint and the section of Detroit with the state’s most polluted ZIP code, 48217.

The Advance on Monday gave you the lay of the land of recent and scheduled campaign stops.

Here’s our updated roundup:

Hakeem Jeffries, Brenda Lawrence fundraiser

On Tuesday, U.S. Reps. Hakeem Jeffries (D-N.Y.) and Brenda Lawrence (D-Southfield) are hosting several of the candidates for a fundraiser at the Whittier.

Candidates confirmed for the event so far include U.S. Sen. Kamala Harris (D-Calif.), U.S. Rep. Tim Ryan (D-Ohio), U.S. Rep. Tulsi Gabbard (D-Hawaii) and U.S. Sen. Kirsten Gillibrand (D-N.Y.). Tickets for the event start at $50, and the meet and greet is scheduled to begin at 5 p.m.

‘Doubleheader in the D’

Gov. Gretchen Whitmer — who’s been a fixture on national TV ahead of the debates — and the Michigan Democratic Party are teaming up for a two-night fundraiser on Tuesday and Wednesday evening.

They’re expected to host several of the presidential candidates at IBEW Local 58 in Detroit, but so far, none have been publicly confirmed as attending the reception. Tickets for the event cost $100 per person, per night.

Jay Inslee meets with Muslim leaders in Detroit

After unveiling his Community Climate Justice Plan in Detroit and touring the Flint Development Center on Monday – including shooting some hoops with Flint kids – Washington Gov. Jay Inslee will visit a Detroit mosque and hold a roundtable with Muslim leaders Tuesday morning.

Inslee made his first visit to Michigan in June, touring the state’s most polluted ZIP code and holding an environmental justice roundtable. Inslee also was the first presidential candidate to call for Enbridge’s Line 5 to be shut down. Since then, Sanders has said he agrees.

Kamala Harris visits local businesses in Detroit

Harris visited two Detroit businesses – the Narrow Way Café and Good Cakes & Bakes – on Monday afternoon, just before picking up the endorsement of the Michigan Democratic Party Black Caucus.

The Advance also reported that Harris has been spotted at non-campaign events in the D, including a music concert on Saturday.

Supporters are encouraged to attend a pre-debate party outside Comerica Park on Wednesday at 5 p.m., although it is unclear whether Harris will be stopping by the event.

Michael Bennet meets with union apprentices

U.S. Sen. Michael Bennet (D-Colo.) will discuss workforce development and health care with union apprentices in Troy on Tuesday afternoon. The event is not open to the public.

Andrew Yang fundraiser

Despite getting relatively little time at the first debate, entrepreneur Andrew Yang has still been building momentum on social media and is now only one poll away from qualifying for the third and fourth debates. Yang hopes to capitalize on that momentum with a fundraiser at TechTown Detroit on Tuesday evening.

Yang was the first candidate to visit Michigan in the 2020 cycle, holding a rally in November 2018.

Tulsi Gabbard watch party

After the debate Wednesday night, Gabbard will visit her official debate watch party at Bookie’s Bar and Grill.

John Delaney roundtable, press conferences

Former U.S. Rep. John Delaney (D-Md.) will hold a roundtable discussion with minority entrepreneurs in Detroit on Tuesday. The event is being hosted by the Detroit Development Fund, which manages the Entrepreneurs of Color Fund to provide capital to Detroit businesses owned by people of color and that hire primarily people of color.

Delaney also is holding four media availabilities in the days ahead of the debate. He was the second candidate to visit Michigan in the 2020 cycle, hosting a Detroit roundtable in January.

Howie Hawkins meet and greet

Green Party candidate Howie Hawkins, who calls himself the “original Green New Dealer,” is hosting a meet and greet in Detroit ahead of the second debate. The event starts at 12 p.m. Wednesday at the Cass Café.

Pete Buttigieg rallies with Detroit security workers

South Bend, Ind., Mayor Pete Buttigieg will rally with Detroit security workers who are fighting for a union on Wednesday at 10 am in Detroit’s Hart Plaza.

Buttigieg is the second candidate to stand with the workers in person after several candidates tweeted their support. Harris held a rally with the workers last week.

Buttigieg also held a fundraiser in Detroit Sunday evening, where he laid out his plan for winning Midwest states in 2020.

Detroit Rise event with Cory Booker

On Thursday, U.S. Sen. Cory Booker (D-N.J.) will host another event in Detroit. Doors open at 5 p.m. for the event at Saint Andrew’s Hall.

Bernie Sanders fundraiser; Flint, Canada events

Sanders, who narrowly won Michigan’s primary in 2016, held a grassroots fundraiser in Detroit on Saturday evening. Tickets cost $27 and the event sold out.

On Sunday morning, Sanders boarded a bus in Detroit and crossed the border into Canada to buy insulin with people who have type 1 diabetes.

Former Ohio state Sen. Nina Turner and actor and activist Danny Glover also visited two homes in Flint Monday morning to get an update on the water crisis on behalf of the Sanders campaign.

Julián Castro fundraiser

Following his breakout performance at the first Democratic presidential debate in Miami, former U.S. Housing and Urban Development Secretary Julián Castro held a fundraiser Monday evening in Detroit. Tickets for the event, which took place at the Eastern Detroit, started at $10.

Castro became the first 2020 presidential candidate to visit Flint in June, when he toured the Flint Farmers’ Market and held a town hall.
