It seems the phenomenon of "too good to check" can affect almost anybody, as Jeff Soyer, of Vermont points out.
Thus the story falls into the same category as anything you hear about SB-2099, which was also introduced around 2001, and died in committee. Google is your friend.
Fred Maslack did, in fact, while a State Representative, introduce such a bill — in 2000. This was during the run up to the vote to allow civil unions and Maslack wanted to be sure residents of Vermont understood the state’s Constitution. Although a Republican, Maslack was, like most Vermont elected officials, that quirky combination of libertarian values. He also supported a bill in 1996 to legalize medical marijuana.
Anyway, he is no longer serving in the State House.
