From my reading, it was Ohio Republicans who took away the three day extension, and that Obama is trying to correct something that the people were against, but didn’t get a chance to voice in the first place. There is conflicting info being put out, that I’ll have to sort through later. I sincerely hope, that Republicans were not the ones to undermine the military.
Yes, Republican lawmakers in Ohio reduced the number of days people can vote early, in-person.
Then the Dems decided to put it on the ballot in November to repeal it.
Republicans then, to avoid having it on the ballot, passed a new bill taking back nearly everything except for the reduced early voting.
Obama's campaign then sued, saying if military gets extra voting days everyone should get it.
That's the easy version of events.
