In Iowa, 76 percent of eligible voters cast ballots last November, among the highest rates in the nation, as Republicans swept races up and down the ballot.
As Republicans march ahead with their campaign to tighten voting laws in political battlegrounds, some in their party are worried the restrictions will backfire by making it harder for GOP voters to cast ballots.
The restrictions backed by Republicans in Georgia, Florida, Iowa, Texas and Arizona often take aim at mail voting, a method embraced by voters from both parties but particularly popular with older voters. The new rules, concerned Republicans note, may be billed as adding security or trust in elections but ultimately could add hurdles for key parts of the GOP coalition.
