Minority-group voters are so "gullible" they believe fabrications about voter suppression concocted by Democrats, one of the most combatively conservative Republicans in Congress maintains.

"The Democrats lie when they say, 'Oh, this is to suppress votes,' or 'This is to hurt minorities.' It's just a lie," Rep. Doug Lamborn said on a recent conservative radio broadcast getting some decent recirculation on social media, from both fans and foes of his thinking. "They want to stir up minorities who are gullible and believe that garbage."

The comments are a sharp rhetorical escalation in one of the most intense partisan disagreements over how to improve American democracy: Republicans maintain that their interest in strict rules surrounding voter registration and access to the polls is all about preventing voter fraud, and Democrats counter that the GOP sees its easiest path to victories in contests where turnout is held down by such rules.
