Nuclear option

The Biden administration is trying to get rid of the filibuster saying the nuclear option would used on a one time basis to pass the Voting Rights Bill. Two democratic senators are holding out and the bill will not pass without their help. If this did pass would there be another one time use in a few weeks to pass statehood for Washington DC and then in a few more weeks a bill to increase the number of justices. If the Voting Rights Bill were to pass it would be challenged in court and with the current court it would likely not pass much like the 6 to 3 vote today on the mandate to force business to make employees wear mask and get vaccinated.
