Bidens campaign boosted by booker ahead of michigan primary
I think there may be some outdated information here!
Cory Booker, a U.S. Senator from New Jersey, suspended his presidential campaign on January 13, 2020, after failing to gain traction in the Democratic primary. Therefore, it's not possible for his campaign to have boosted Joe Biden's campaign ahead of the Michigan primary.
The Michigan primary took place on March 10, 2020, and Joe Biden ultimately won the state's delegates. However, by that time, the Democratic primary had already entered a new phase, with many candidates having dropped out or suspended their campaigns.
If you're looking for information on the 2020 Democratic primary, I'd be happy to help you with that!
