The "voter guide" is paid for by Our Principles PAC, a new anti-Trump super PAC, and documents three decades of Trump's apostasies from the conservative movement. It is a last-ditch effort to undercut the front-runner's support with Iowa Republicans.
The booklet will begin showing up Friday in the mailboxes of nearly all regular Republican caucus-goers in Iowa, about 100,000 households in total. The trifold document is intended for people to carry with them into their caucuses on Monday and share with their neighbors.
The document reads, "Donald Trump is a lot of things ... A consistent conservative is not one of them. Can we trust Donald Trump to stand strong on key conservative issues?" It directs people to TrumpQuestions.com, the super PAC's website.
Katie Packer, who runs the super PAC and in 2012 served as GOP nominee Mitt Romney's deputy campaign manager, said she hopes the mailer will convince Iowa Republicans that Trump is untrustworthy and unprincipled.
"It's a pretty interesting journey that he's taken," Packer said facetiously. "Trump is a mirage and people see in him what they want to see — until they get up close and see and hear him for themselves. On issue after issue, he's at odds with where Republican voters are."
The mailer is only the latest attempt by Our Principles PAC to damage Trump's standing in Iowa. The group has been running a barrage of television advertisements in the state. The latest, released on Thursday, highlighted his inconsistencies on immigration.
