Absolutely not, since it's an obvious power grab for the sole political benefit of the Democratic party. And DC already has enough power and influence.
Although there is a legitimate argument to be made for P.R. statehood, but not for D.C. statehood. it's too bad PR doesn't have the military strategic benefits of Hawaii/Alaska/Guam etc... in which case I'd support it fully.
Is refusing to give DC representation in congress because of their political leanings not a form of voter suppression? They are Americans living in America, who deserve the same political rights as all Americans. It doesn't matter how they lean.
