The candidate filing deadline may be nearly six months away, but it seems increasingly likely that the fight for the Democratic nomination in Iowa's third Congressional district will be a two-way contest between Desmund Adams and Jim Mowrer. Today Representative Dave Loebsack (IA-02), the only Democrat left in Iowa's Congressional delegation, made his "full support" for Mowrer official. I enclose the statement from Mowrer's campaign after the jump. It includes a list of well-known endorsers, such as former Lieutenant Governor Sally Pederson, State Senators Dick Dearden and Bob Dvorsky, State Representatives Charlie McConkey, Todd Prichard, and Abby Finkenauer, former Iowa Democratic Party chair Sue Dvorsky, three IDP State Central Committee members, and Democratic Party chairs in five IA-03 counties.
Endorsements at this stage are not aimed at persuading Democratic primary voters. Rather, they serve mainly to deter other candidates from getting into the race. They also signal to donors inside and outside Iowa that Mowrer is the "serious" candidate. He already was likely to raise substantially more money than Adams, by virtue of his strong fundraising effort as the 2014 Democratic candidate against Representative Steve King in IA-04.
On a related note, last month the Cook Political Report changed its rating on IA-03 from "toss up" to lean Republican. One reason: "Each day Mowrer consolidates support, the less likely it is that Democrats' very top choice, U.S. Attorney Nick Klinefeldt, gets in. Former Gov. Chet Culver was rumored to be interested but now looks unlikely to run." I'm intrigued that a handful of unnamed sources (including one "operative") managed to convince beltway experts that Klinefeldt would be the "gold standard" candidate in IA-03. Not meaning to knock Klinefeldt, but I've had scores of conversations with local Democrats about this race. It's hardly a consensus view that the U.S. attorney would be the strongest possible candidate to face first-term Republican David Young.
Speaking of Young, earlier this month James Hohmann and Elise Viebeck reported for the Washington Post that he had signed a contract with the National Republican Congressional Committee as a condition for getting help from the NRCC's incumbent protection program. You can view the fundraising, communication, and political requirements laid out in that contract here.
The sixteen counties in IA-03 contain 150,572 active registered Democrats, 163,096 Republicans, and 163,748 no-party voters, according to the latest figures from the Iowa Secretary of State's office. More than half of the district's voters and roughly two-thirds of the Democrats live in Polk County, containing Des Moines and most of its suburbs.
