The Brennan Center for Justice is tracking more than 250 bills to restrict voting by lawmakers in 43 states.

Benjamin Ginsberg, an elections lawyer who has represented past Republican presidential nominees, lamented the death of the “ideas factory” in the GOP.

“Tell me what the innovative Republican policies have been of late?” he said. The focus on re-litigating the last election is “probably a sign that the Republican Party is mired in a bit of a policy wasteland and doesn’t know which way to turn to get out.”

Alberto Gonzales, the former attorney general in the George W. Bush administration, said “all Americans should be concerned about election integrity.” But with no evidence of widespread fraud beyond normal irregularities, he said, the focus by some in the GOP on the last election is a “big distraction” from issues that are more pressing to the electorate.
