Ohio state Rep. Todd Book (D) is dropping his 2010 campaign against Rep. Jean Schmidt (R), a setback for Democratic officials who had been promoting his candidacy in the Cincinnati-area 2nd district.“I have decided I cannot commit the necessary time to run for the U.S. Congress. This was not an easy decision, but it is one that was made with the best intentions for my family, the good people of southern Ohio and the Democratic Party,— Book said, according to the Portsmouth Daily Times.Book announced his candidacy in late July, and since then had drawn the backing of Gov. Ted Strickland (D) and the Ohio Democratic Party. But he reported raising just $64,000 in this year’s third quarter, and the Cincinnati Enquirer said a labor organization recently rescinded its support of Book’s campaign.Book’s withdrawal leaves David Krikorian, who has a background in business, as the only Democratic candidate opposing Schmidt at the moment. Krikorian ran as an Independent in 2008, winning 18 percent of the vote in a race in which Schmidt won 45 percent of the vote and runner-up Victoria Wulsin (D) took 37 percent of the vote.Schmidt faces opposition in the Republican primary from Mike Kilburn, a county commissioner.
