Yes, but that's after admitting DC as a state
The problem is I don't see 50-51 seats being enough to admit DC as a state.
Not a single Democratic Senator will oppose it. There is no argument against it (assuming you exclude the federal buildings) beyond "They might elect Democrats/blacks to the Senate, and I don't like that." No Democrat is going to stand up for taxation without representation, for Americans denied a voice in Congress altogether.
Once it's going to pass anyway, you'll probably see some Republican support too, just for the optics.
I was assuming that DC statehood could still be filibustered, and my point was I'm not sure if there's enough numbers to nuke the filibuster.
Although if Angus King is saying "do it", then.....
