Well... That is one idea floating around among Democrats because that would essentially get rid of the unfair Republican advantage in the Electoral College and Senate (compared to the popular vote distribution between the two parties). However, I do not see anything happening regarding that issue anytime soon. Republicans will never willingly surrender their advantage. If both of them gain statehood, it will be a lot more difficult for them to win presidency and/or Congress (especially if you consider how some big R states like Texas are turning more blue each election).
