Correct me if I’m wrong, but it seems that overall turnout in Iowa in 2008 was lower than it was in 2004. That is surprising, given the well-documented surge in new voter registrations.

Which people who participated in 2004 stayed home yesterday, and how did that affect the results?

Tom Harkin won all 99 counties, which is remarkable considering that John McCain beat Barack Obama in 46 or 47 of Iowa’s counties. Even in Republican areas, they’re looking for more in a U.S. senator than trash talk and smackdowns. Does anyone remember whether Chuck Grassley carried all 99 counties in 2004?

(UPDATE: The Daily Kos election scoreboard shows Christopher Reed beating Harkin in Page County in the southwest part of the state and in the four counties in the northwest corner. There may be a mistake on the Des Moines Register’s map, which shows all 99 counties in blue for the Senate race.)

The words “idiot” and “insane person” will be removed from the Iowa Constitution.

Speaking of idiots, Steve King got away with barely campaigning in the fifth district, winning by at least 20 points. Politics can be cruel, and I feel for Rob Hubler, who worked so hard for so long to give fifth district residents a credible candidate.

Nationwide, many Democratic challengers in districts like IA-05 fell far short. Nancy Boyda, a surprise winner from 2006 in KS-02, was a surprise loser last night. The Democratic Congressional Campaign Committee invested millions of dollars in other similarly Republican districts like MN-06 and AZ-03, and our challengers lost those too.

After beating Kim Schmett by 57 percent to 42 percent (about double his margin of victory in 2006), third district Congressman Leonard Boswell immediately vowed to run for re-election in 2010. Can’t some Democratic heavy-hitters who are on good terms with Boswell encourage him to retire? Barring that, is there anyone willing to start fundraising for a 2010 primary challenge who would have some establishment support?

We may have to run against Tom Latham in a redrawn third district in 2012, and it would be helpful to have a new Democratic incumbent in place before that happens.

Bruce Braley was the incumbent re-elected by the largest margin, 64 percent to 36 percent. I agree with John Deeth that Republican moderates are going to challenge Dave Hartsuch in his 2010 state senate primary.

Dave Loebsack won big in the second district, by 57 percent to 39 percent. The hill in this D+7 district is just too steep for a Republican candidate to climb. Mariannette Miller-Meeks would be better off seeking a different political office in the future, although the Iowa GOP may encourage her to run for Congress again in 2010. Loebsack won’t have the Barack Obama turnout machine cranking in Johnson and Linn counties two years from now.

Iowa Democrats are looking at small net gains in the House and Senate. Dawn Pettengill got away with switching to the GOP after the Iowa Democratic Party worked hard to elect her. A couple of races may have a different result once the absentee and provisional ballots are counted. Deeth has more details.

Jerry Sullivan has not ruled out requesting a recount in House district 59, although it seems unlikely to me that there are enough provisional and absentee ballots outstanding for him to reverse Chris Hagenow’s 141-vote lead (out of more than 16,000 votes cast).

UPDATE: Johnson County voters narrowly approved a controversial bond measure. The proposal was designed to generate

$20 million in a 20-year period to conserve open space.

By collecting taxes for two decades, the Johnson County Conservation Board will have the funds to buy and preserve remnant areas of land scattered throughout the county from willing sellers.
