On June 6, SaintPetersBlog released results of a poll for the U.S. House race, 13th district. The only candidates on the ballot are Republican incumbent David Jolly and Libertarian Lucas Overby. The results: Jolly 47%, Overby 31%, undecided 22%.
This is the first neutral professional poll ever conducted for a U.S. House race between just a single major party nominee and a minor party nominee, as far as is known. Generally when there is only a single major party candidate running, no one is motivated to spend the money to conduct a poll. This race is unusual. Generally when only a single major party person is running, the district overwhelmingly favors the party of that single major party candidate. But this district is fairly closely balanced between the two major parties. In November 2012, this district voted 50% for President Obama and 49% for Mitt Romney.
The highest share of the vote any Libertarian nominee for U.S. House ever received was 31.55%, in the November 2012 election for the Kansas 3rd district, centered on Kansas City. That was also a two-candidate race between a Republican and a Libertarian, Joel Balam. Thanks to IndependentPoliticalWire for the link.
