LANSING (AP) — Gov. Gretchen Whitmer has launched a four-day bus tour across Michigan with Democrat Joe Biden’s presidential campaign before the Nov. 3 election.

No passengers will actually be on the bus, due to the coronavirus pandemic. Democrats instead will travel in a caravan of vehicles.

The tour started Friday in Taylor, a Detroit suburb, with a rally hosted by Lt. Gov. Garlin Gilchrist II and U.S. Rep. Debbie Dingell. Whitmer, a co-chair of Biden’s campaign, plans to appear at some events over the four-day period.

The “soul of the nation” tour is designed to promote early voting and boost support not only for Biden but other Democrats on the ballot. Stops will include car rallies, sign distributions, early voting sites, absentee ballot drop boxes and volunteer mobilization events.
