Democratic senator slams Trump administration’s various policies and is close to the all-time record held by Strom Thurmond (24 hours and 18 minutes)

US voters are headed to the polls on Tuesday in Wisconsin and Florida in elections that some see as a test of Donald Trump’s popularity and the political clout of his billionaire ally Elon Musk.

The most closely watched contest is a battle for a seat on Wisconsin’s seven-member supreme court. Conservatives are trying to flip ideological control of the court, which currently has a 4-3 liberal majority. The contest, which features liberal judge Susan Crawford facing off against conservative Brad Schimel, will have huge consequences in the state.
