Good news for Iowa political junkies who value sleep: there’s no need for an all-nighter to follow this year’s primary results. In the most closely-watched races, it was clear less than an hour after polls closed that Fred Hubbell will be the Democratic nominee against Governor Kim Reynolds, Abby Finkenauer will face off against Representative Rod Blum in Iowa’s first Congressional district, and Cindy Axne will challenge Representative David Young in the third Congressional district.

I’ll update this post frequently throughout the evening as results are reported.

The latest fundraising numbers from Iowa’s first Congressional district confirm what was already apparent: Representative Rod Blum is among the country’s most vulnerable U.S. House incumbents, and Abby Finkenauer will be the prohibitive favorite in the June 5 Democratic primary.

Follow me after the jump for highlights from the first-quarter Federal Election Commission filings for Blum and his four challengers.

It’s been too long since Bleeding Heartland checked in on the campaign in Iowa’s first Congressional district. Two-term Representative Rod Blum is not only our state’s most endangered U.S. House member, he is among the country’s most vulnerable GOP incumbents, according to leading election forecasters.

Recent revelations about Blum’s shady, undisclosed internet company may further undermine his election prospects. Tin Moon used Blum’s chief of staff in a fake testimonial, touted phony client “success stories” on its website, and solicited business by promising to make FDA warning letters harder to find in online searches.

The main political arm of U.S. House Democrats is officially promoting Abby Finkenauer as its preferred candidate to take on Representative Rod Blum in Iowa’s first district.

Finkenauer was among the initial group named to the Democratic Congressional Campaign Committee’s “Red to Blue” program for this election cycle, as first reported by Roll Call’s Simone Pathe on November 15. House Minority Whip Steny Hoyer and Representative Jimmy Panetta were featured guests at a Cedar Rapids fundraiser for Finkenauer’s campaign on November 19.

Republican Representatives Rod Blum and David Young have approval ratings below 40 percent and re-elect numbers below 50 percent, according to new surveys from Public Policy Polling.

The Patriot Majority Fund, a super-PAC that largely opposes GOP incumbents, commissioned polls in nine House districts around the country, including the two in Iowa that Democrats will target next year.
