Elon Musk and Richard Uihlein — have spent $2.8 million on TV ads helping Supreme Court candidate Brad Schimel.

Individual donors aren't allowed to give more than $20,000 to a Supreme Court candidate. But both Republicans and Democrats use a workaround to solicit bigger donations.

Building America's Future, an Elon Musk-backed dark money group, has already purchased more than $670,000 of air time backing Brad Schimel.

In this instance, Joe Ricketts, an owner of the Chicago Cubs, gave $500,000 to the state GOP. After that and some other large donations, the party gave about $1.7 million to Brad Schimel’s campaign.

The digital ad run by Building America's Future features a photo of Susan P. Crawford, a Harvard professor, not liberal candidate Susan M. Crawford.
