The House Committee on Oversight and Reform is holding a hearing regarding making D.C. the 51st state. The idea of D.C. statehood is not new. In fact, it's been around since the framing of the Constitution (see Article I, Section 8, Clause 17), thus a constitutional amendment would be required to make D.C. into a state.
If you've followed D.C. city politics for any amount of time, you'll realize why Democrats would LOVE to get their hands on it as an additional state.
But statehood isn't just a constitutional concern, it's also a racial concern, apparently. According to former Secretary of Labor Robert Reich, it's racist to oppose statehood.
This is a fun game! Mississippi has four million black citizens and two senators. 39% of Californians are Hispanic, and they get two senators too! It's almost is if every state gets two senators regardless of their demographic makeup. D.C. would get the same number of senators if it were a state, but it's not, and it was never intended to be one sooooo 🤷
The Family Research Council sums the issue up well:
Knowing what we know from past budgets and laws proposed by the D.C. City Council, a "state of D.C." would almost certainly support policies that undermine the sanctity of human life and are detrimental to the American family. A state of D.C. would most likely contribute two more votes for such policies in the U.S. Senate (as well as a yet undetermined number of votes in the House), directly impacting millions of Americans nationwide.
I think we can see quite clearly what the argument for statehood for Puerto Rico will be.
