... could they significantly swing senate seats?

Those are the folks that work remotely all the time. I wonder how many there really are and if they could time a few months residency in swing states to alter that map that we've all probably seen of the population represented by each senator...

Maybe something to look into for those in blue states with big cities that have the ability to temporarily change residency at particular times for a few months each election cycle. (Retirees?)
