The legislative boycott by Indiana’s House Democrats pales in comparison to this one from Rhode Island in January 1923. It lasted all year and featured a fistfight and a gas ‘bomb.”
The Rhode Island Senate Democrats were fighting to change how the Senate districts were drawn at the time. Apparently, the 22 Republicans represented 24% of the population while the 18 Democrats represented 74%. (I assume the remaining two percent is some kind of rounding issue.)
