Mike Glover of the Associated Press wrote a piece this week on the huge money advantage that Senator Tom Harkin and Iowa’s five U.S. House incumbents have over their opponents.

I’ll have more to say on this topic in future posts, but for now I want to note one thing: although nearly all incumbents are able to outspend their opponents, that advantage is not always enough to overcome a national tidal wave toward the other party.

Bruce Braley, Dave Loebsack and Leonard Boswell all represent districts with a Democratic tilt (of varying degrees) in what is likely to be a very big Democratic year.

The odds-makers might favor Tom Latham and Steve King now, but in a big year for the challenger’s party, money and the other advantages of incumbency are not always enough to win.

Just ask Neal Smith, who was an 18-term incumbent and had more clout than any Iowan currently serving in the U.S. House. I can’t find campaign finance statistics going back that far, but I would bet that he spent more trying to keep his seat in 1994 than Republican Greg Ganske spent in taking him down.

Democratic House Speaker Tom Foley spent “what aides say may total $1.5 million to $2 million, a staggering amount for a House race” in 1994, but he still lost to George Nethercutt in Washington’s fifth district.

Chris Bowers had the most accurate final House forecast in 2006. But what did he write in his first forecast following several states’ primaries in September of that year?

And in his final House update, published on November 6, 2006, Bowers still had Shea-Porter’s race in the “likely Republican” category, commenting, “If she wins, Carol Shea-Porter will become a legend.”

Her shocking victory in New Hampshire’s first district over an entrenched Republican incumbent was indeed legendary.

Obviously, it’s better for a challenger to have as much money to spend as possible, which is why you should donate to Rob Hubler and Becky Greenwald, and why I would like to see our ultra-safe Democratic incumbents giving more to the DCCC and DSCC.

But I strongly disagree with the contention that a money advantage makes Tom Latham and Steve King as safe as Iowa’s Democratic incumbents this year.

UPDATE: In the comments, riverdog9 asked why I would encourage people to give to the DCCC instead of directly to the candidates. That was not my intention, and I apologize for any misunderstanding.

To clarify, individual Democratic voters should give directly to the Congressional candidates, unless you’re one of those people who can afford to give more than the maximum donation of $2,300 to a candidate for federal office. In that case, you should give $2,300 directly to the candidate and any extra money to interests groups that are supporting that candidate.

Safe Democratic incumbents should give more to the DCCC and DSCC, because campaign finance law allows unlimited transfers of funds from members of Congress to those committees, and unlimited expenditures by those committees on behalf of candidates in individual districts.
