John Mertens, an engineering professor, is running for U.S. Senate in Connecticut in 2010 on a platform of abolishing federal subsidies for ethanol. He says such a step would save $70,000,000,000 per year and also help the environment. He says he is an independent candidate, but that he also is seeking the nomination of the Independent, Green, Libertarian, and Connecticut for Lieberman Parties. See this story.
Connecticut would permit him to appear on all those party lines, but the Green, Libertarian and Independent Parties are not ballot-qualified for U.S. Senate in 2010. They are qualified for certain other races. In Connecticut, a party is ballot-qualified for each race for which it polled 1% in the last election (it is also ballot-qualified for all office if it polled 20% for Governor in the last gubernatorial election).
The Connecticut for Lieberman Party is ballot-qualified for U.S. Senate in 2010. Mertens would need 7,500 signatures to appear for as the nominee of any of the other parties.
