One of Trump's justices just suggested blocking state courts from protecting voting rights: analysis

On Monday, the Republican-appointed justices on the Supreme Court rejected a push to expand Wisconsin's ballot processing deadline so that votes received after Election Day will count, as long as they are postmarked by the proper day.

But according to Slate legal journalist Mark Joseph Stern, Justice Brett Kavanaugh signaled he would have been willing to go even further — and embrace a legal theory saying that not only should federal judges be blocked from expansion of voting rights ahead of elections, but state judges should be as well.

Such a theory, Stern noted, was suggested by right-wing former Chief Justice William Rehnquist in the Bush v. Gore ruling that decided the 2000 presidential election — but not even all the other conservative justices agreed with it.
