Oh, I thought the headline meant remote voting for, you know, voters, not Senators, and was very surprised to see an R next to one of the sponsor's names. The bill's just to let the Senate vote remotely. I'd imagine most of the interesting nuance is about "presence" and quorum-making. This is not about expanding remote/by-mail voting in elections, which Republicans have generally been strongly against, including and especially since the Covid-19 crisis started.
[EDIT] correction: it's not a bill, either, it's (as the headline correctly notes) a resolution to change Senate rules.
