Missouri's 9th congressional district may just take the prize as one of the most mixed-up mixed bags. In Tuesday's primary, voters had to choose from a jumble of candidates with backgrounds, experience and issues that seem as varied as the district itself.

The 9th holds conservative suburbs in part of St. Charles County, rural farmland along the borders of Illinois and Iowa and the liberal college town of Columbia.

So no big surprise that voters usually have few issues to coalesce around. This year, however, the economy, the war, rising prices and a general discontent with the current administration seem to be issues everyone's thinking about.

And the nine candidates from both major parties have campaigned hard on them, too.

Wait -- nine candidates?

That's right. Four Democrats and five Republicans want to represent the 9th in Congress.

The seat is hot because it's open -- a rarity in the district, which was represented by Rep. Kenny Hulshof, a Republican, since 1996 and before that by Harold Volkmer, a Democrat, from 1976 until 1996. Hulshof is running for governor, and many Democrats are hoping now is the time to take the district back.

But can they?

In a year that's generically good for Democrats and generically bad for Republicans, they might. In 2004, 59 percent of people in the 9th voted for President George Bush, according to Congressional Quarterly. But the district has a history of independent voters who usually go Republican, rather than hard-core GOP supporters.

That means Democrats have a shot in a primary race that's featured unprecedented one-on-one debates between Bob Onder, a Republican, and Ken Jacob, a Democrat, over abortion; attention (and often mocking) for a former University of Missouri-Columbia football star, Brock Olivo, who fumbled early on; and brought a few people back into politics who've been out for a while, including Jacob, Democrat Steve Gaw and Republican Blaine Luetkemeyer.

Here's a glance at each candidate, where they come from, what matters to them and how much money they've raised as of July 16, according to the Federal Election Commission.
