Since the day State Senator Kent Sorenson dumped Michele Bachmann for Ron Paul, Iowa politics watchers have speculated that he was paid well to do so. Earlier this year, news emerged of indirect payments totaling $7,500 per month from entities supporting Bachmann to Sorenson while he chaired her presidential campaign in Iowa. Today The Iowa Republican blog’s publisher Craig Robinson posted e-mails and memos detailing a large “payoff” for Sorenson in exchange for publicly endorsing Paul.

I hope these allegations will generate momentum in the Iowa legislature to prohibit lawmakers from being paid by political campaigns. An ethics investigation of Sorenson is pending, but these rules should be written into state law in my opinion. The integrity of the Iowa caucuses is undermined by the perception that presidential candidates can buy state legislators.

I assume that whoever leaked this information to The Iowa Republican is hoping that Sorenson will either resign or lose in a GOP primary to represent Senate district 13 next year. It’s a district Republicans “should” hold, but Sorenson is surely not the best candidate to accomplish that goal. To my knowledge, no Republican has announced plans to challenge Sorenson in a primary. He has passionate defenders in the social conservative wing, thanks to his uncompromising stance on Medicaid abortion funding, his hostility toward an LGBT youth conference, his support for impeaching Iowa Supreme Court justices and bringing back the death penalty, among other issues.

It’s worth noting that Robinson has never been sympathetic to the Ron Paul faction within the Iowa GOP. His website displayed a strong “Rick Santorum” slant in late 2011 and early 2012. Critics have even accused Robinson of taking money in exchange for promoting a certain angle at The Iowa Republican. Still, today’s post on Sorenson’s “payoff” is a must-read.
