From Eric Dondero:

A curious development out of the Hoosier State. It seems for some reason, internet hoaxers pulled a fast one on the Libertarian Party of Indiana, for reasons unknown. A Republican State Senator was also apparently victimized.

From WBIX.com:

The Libertarian Party of Indiana wants answers after a being a victim of a hoax email.

Executive Director Chris Spangle says they received the email on February 9, from whom they believed was Republican State Senator Connie Lawson.

Spangle says the email was about the party's opposition to the gay marriage constitutional ban and threatened if they didn't change their opinion on the issue, that "structural changes would be made."

The OhioRepublic blogspot reports:

The Indiana Libertarian and Republican Parties are co-operating in the investigation.
