A Washington Post article explaining the contradictory Supreme Court decisions:
"And when he wrote a short opinion, it was somewhere between liberals who believe dramatic accommodations are warranted during a pandemic and conservatives who say the judiciary should not second-guess state legislatures, who are entitled to set the rules.
Roberts is skeptical of federal judges intervening in those decisions, but defers when state courts and election boards step in.
So Roberts, along with his fellow conservatives, has blocked changes imposed by federal judges in Alabama and Wisconsin. But he has been open, along with the court’s liberals, when state actors — the Pennsylvania Supreme Court, and election officials in Rhode Island and North Carolina — agree to loosen restrictions."
