Wisconsin court election poses key test for Musk as kingmaker

It's only been five months since voters in Wisconsin faced a bitterly fought election, but residents of the US state are already heading back to the polls.

This time, Elon Musk looms large in the race to fill a vacancy on the Wisconsin Supreme Court, even if the billionaire's name doesn't appear on the ballot.

It's the most expensive judicial contest in US history, with more than $90m (£70m) spent so far, including $20m from Musk and groups affiliated with him.

The choice is between conservative Brad Schimel, backed by President Donald Trump and Musk, and liberal Susan Crawford, who is supported by former President Barack Obama and Democratic mega-donors like George Soros.
