We had straight ticket voting in IL until it was abolished by the lame duck GOP legislature in late 1996, after the dems had used it one last time to take back the lower House by a slim margin.
“We don’t have a closed primary but you can’t split a primary ticket and vote GOP in one race and democrat in the others. “
Did MI ever have that? Cali and WA did, the Supreme Court struck it down in 2000. Now they’ve both gotten around the ruling by going to a “top-two” primary.
with blago as il gov, straight ticket voting came back.
