Iowans have listened to tens of millions of dollars worth of campaign ads for these Caucuses. Thousands of phone calls have been made and mailboxes have been stuffed with campaign literature. Now, on the eve of the Caucuses, there’s a dust-up over a campaign mailer from the Ted Cruz campaign.

This is how Donald Trump described it today during a stop in Sioux City: “It’s like an oficial document being sent to people in Iowa that they have to get out and vote because they’re in violation, and then they have grades for different things and it says ‘F’ and it’s terrible. I’ve never seen anything like it.”

Ted Cruz says Iowa Republicans have seen something like it. Cruz told reporters in Sioux City on Saturday that it’s a “routine” type of mailing like one used by the Republican Party of Iowa in 2014.

“I will apologize to nobody for using every tool we can to encourage Iowa voters to come out and vote,” Cruz said. “Our country’s in crisis.”

Iowa’s secretary of state issued a statement Saturday, saying the mailer “is not in keeping in the spirit of the Caucuses.”
