JOPLIN, Mo. — Money is starting to pile up for candidates planning to run for House of Representatives from Missouri in 2012.

According to information filed last week with the Federal Election Commission, U.S. Rep. Billy Long, of Springfield, has collected nearly $270,000 in campaign contributions for a three-month period ending June 30. U.S. Rep. Vicky Hartzler, of Harrisonville, has taken in more than $347,000.

 The reports listed campaign receipts, spending and cash on hand for Long, incumbent in Missouri’s Seventh District, and Hartzler, in the Fourth District. Both are Republicans who won their seats in 2010; Long took an open seat vacated by Roy Blunt, and Hartzler defeated Ike Skelton, long-time Democrat incumbent.

Financial information on the two, and other candidates, is available on the Federal Elections Commission website.

Incumbency has its advantages, even with freshmen. Long reported nearly $165,000 in individual contributions and more than $95,000 in committee contributions for the three months ended June 30, while Hartzler reported more than $162,000 in individual contributions and more than $158,000 from committees.
