Reuters reports.  A snippet in which I am quoted:

If Pennsylvania’s law is upheld, the state will have to find a way to get the required photo identification to about 750,000 registered voters who the state says lack the kind of ID they’ll need on Election Day.

That could lead to a raft of lawsuits after the election, if voters do not have enough time to get the right ID or if election officials do not implement new laws uniformly across the state, Hasen said.

“If you write a play you wouldn’t premier it on Broadway,” Hasen said. “If you implement a brand new law in time for the presidential election, it could just be bad.”
