Far more likely is suddenly showing an interest in people's safety, and introducing hugely draconian polling measures, which mainly impacts cities which are of course blue. Loads of poll workers are actually retirees, and volunteers. Are they going to risk their lives to do it this time? Should they be? Of course not. So I President Trump have decided no poll workers over 65, for health reasons. That may mean some polling locations are unable to operate, but it's all we can do for the greatest generation.
The GOP will also reduce funding and help with signing up new voters, getting access to ID, or even just physically getting to voting areas (buses etc).
Expect them to also try to get as many police and potentially even army to 'help ensure fair elections' by walking, standing and monitoring places with guns - thus discouraging certain demographics to be comfortable voting.
GOP is now the party of voter suppression, and just like all the other genuinely evil parts of their platform, they execute it with zeal and efficiency. And despite all the polls in June, momentum swings both ways and we all kno this is going to be another election decided on the fringes, so effectively stopping voting in a Milwaukee, or Philadelphia could genuinely swing the whole damn thing, because America's system is so stupid.
