Now maybe this doesn’t mean anything.  Perhaps opposition to voter ID is just an article of faith in blue states, and unsurprisingly they also vote blue.  Maybe.

But maybe not.  Making voters show photo ID seems intuitively likely to reduce fraud, as it makes it harder for people to pretend to be someone else.  Maybe it’s people pretending to be other voters to get another vote; maybe it’s people pretending to be voters who are dead or inactive in order to get another vote, but making people show a trustworthy photo ID when voting makes such fraud much more difficult.

At any rate, the GOP should make a national photo ID requirement for federal elections a top priority in the next Congress.  And it should go further.
