It seems more likely they think they would win more often if there wasn't a voting season, rather than an election day, with a body of folks that tend to follow the rules. While they understand the opposition has no issue with vote harvesting, collecting ballots at old folks homes after "helping them" fill out their ballots, running voter registration booths without the party tag and tossing the ones that aren't registering as Democrats and, finally, who actively oppose any measure that may stop non-citizens from voting which has no purpose other than to ensure that they get the vote from non-citizens.
