In that campaign, which Reed lost by more than 20 percentage points, the Marion Republican claimed that Harkin’s support for same-sex marriage also meant he supports marriage between “any 2, 3 or multiple people of any and all sexes. Heck, as far as he is concerned, you could marry your horse if it makes you happy.”

During a debate later in the campaign, Reed said Harkin had “an eight-year history of becoming the Tokyo Rose of Al-Qaeda and Middle East terrorism.”

In an interview Thursday with conservative blogger Craig Robinson, Reed said he learned a lot from his 2008 defeat and promises a campaign that focuses less on personal attacks and more on the issues.

“Last time, I took the race personally. This time, it’s about the people. So the vitriol and the remarks are not going to be there this time because there is too much at stake. This campaign has to be about defeating Dave Loebsack and what he votes for in Washington.”

Reed is expected to square off in a primary with Mariannette Miller-Meeks, the party’s 2008 nominee in the 2nd district, and Steve Rathje, who Reed defeated in 2008 for the right to take on Harkin.

Yet despite the low-to-invisible profile of Harkin’s Republican opponent, Christopher “Who?” Reed, Wednesday’s KCCI poll showed the businessman and first-time candidate with 39 percent of the vote. That might not sound like much, but with near-universal name ID, John McCain got the same 39 percent in that same poll.

A Research 2000 poll shows Reed at 40 percent, and the Des Moines Register poll had him at 34 percent two weeks ago, with Harkin in the low 50s in each.

So how the heck does Reed, who’s raised almost no money, has a campaign website that looks like a homemade nightmare straight out of 1996, and has Republicans openly talking about writing in one of the primary losers, even get to the mid-30s to low 40s in a poll? Who IS this guy?

Simple. He’s not Tom Harkin.

To Iowa Republicans, “Tommy the Commie” is the Democrat they love to hate, just as lefties bristle at the mention of Steve King’s name. There’s enough of a Harkin-hater base that he’s never broken 60 percent, let alone seen the 70 to 30 margins Republican Chuck Grassley gets every six years.

Despite his work on the farm bill as chair of the Senate Agriculture Committee, Harkin was denied the Farm Bureau “Friend of Agriculture” endorsement, which went to all five Iowa incumbent House members. Farm Bureau endorsements are determined by votes of each county Farm Bureau, and many western Iowa counties will simply never back Harkin.

Iowa saw revolving door Senate seats through the 1970s. With four defeats (Miller, Clark, Culver, Jepsen) and two retirements (Hickenlooper, Hughes), no Iowa senator was re-elected from 1966 to 1986. In contrast, we now have two high-seniority Senate leaders, one in each party.

Running against Grassley has been the loyal duty of a series of eastern Iowa liberals — Jean Lloyd-Jones, David Osterberg and most recently Art Small in 2004, who would have been a really good challenger in 1986 when he ran for lieutenant governor instead. They all struggled to break 30 percent. Grassley gets all the Republican vote, virtually all of the independent vote, and even picks up votes from Democrats who like his aw-shucks persona.

In contrast, Harkin has had top-tier battles until now. The senator likes to brag that he’s defeated more Republican congressional incumbents than anyone in history — Bill Scherle in 1974 for his first House win, Roger Jepsen in 1984 to take the Senate seat, and Tom Tauke, Jim Ross Lightfoot and Greg Ganske since.

It’s safe to say Republican leaders were hoping for a similar profile in 2008. But House members Tom Latham and Steve King saw what looked like a good Democratic year and figured their reelection chances were better. (However, Latham has a real race against Becky Greenwald on his hands, and King has an unflappable opponent in Rob Hubler.) Democrats are likely to pick up five and perhaps as many as 10 Senate seats, and only one Democratic incumbent, Mary Landrieu of Louisiana, is even remotely in trouble.

So Iowa Republicans saw a three-way, flip-a-coin primary between unknowns, and the coin almost landed on its edge. Former legislator George Eichhorn, a late recruit to the race, nearly demanded a recount, but that fell victim to the flood. In retrospect, losing reelection to the state legislature may not have been the strongest launching pad for a U.S. Senate race.

Reed has raised almost no money and didn’t even formally organize a campaign committee till after he (barely) won the primary. He got negative attention for spending some of what little he has raised on clothing and haircuts.

Some Republicans are concerned enough, and hopeless enough, that there have been reports of a write-in effort on behalf of Steve Rathje, who spent two years running for the seat only to come in third in the primary. “We need a U.S. Senator who has the ability to think outside the box and respond with real answers based on new ideas, instead of the opinions he happens to hear on WHO, Hannity and Colmes, Rush Limbaugh or Bill O’Rielly,” wrote Clayton County Republican chair Gwen Eilers in a mass e-mail.

So, what’s a Harkin hater to do — vote for the little-known Linn County businessman who’s on the ballot, or write in the other little-known Linn County businessman who lost the primary? “As a Republican leader, Eilers should support our candidate, Christopher Reed — or step down,” writes state central committee member David Chung on his Hawkeye GOP blog, adding, “Nothing personal, but why Rathje? Wasn’t Eichhorn second?”

One of the first things candidates are taught is: if someone else can do something for you, let them. A candidate should spend all her or his time doing stuff only the candidate can do — meeting voters, the bulk of the fundraising and the human being jobs of parent and/or partner. Yet Reed, on his Web site, bragged about saving campaign cash by driving to Kansas City to pick up the yard signs. Himself.

That also drew criticism from Eilers, who said Reed should have spent the money with an Iowa vendor. “He cannot and will not win.  That is the truth,” writes Eilers, who hopes that Rathje’s write-in total will top Reed’s votes and send a message.

Chuck Grassley’s races have given political sabermetricians useful statistics on straight-ticket Democratic voting levels. He regularly rolls up 99-county wins, and even precincts that go for Grassley opponents are few and far between.

For the first time, Tom Harkin has a race like that. The end result of this race will be a set of statistics, a precinct-by-precinct measure of the base Republican vote, which is probably about 10 points higher in Iowa than the yellow dog Democratic vote. But Reed will likely carry several counties in the northwest, just by being on the ballot as Not Tom Harkin.
