In the current debate over whether the District of Columbia should be admitted as a State, Congressman Jamie Raskin (D, MD) made this claim.

All that they [Republicans] see is two new liberal Democrat senators, but that cuts against everything that we believe in about American democracy. We do not deny people the right to vote based on our expectation of how they will vote.

What the Democratic Party and its politicians do, though—until the Civil War they forced over their demand to keep slaves—is demand that any State admitted to the United States as a Free State be balanced by the admission of another State as a Slave State—so that those Senators could be voted for by slaveholders.

Raskin knows the history of his Progressive-Democratic Party full well. Of course the move to admit DC as a State is all about getting two more of his Progressive-Democratic Party Senators. His Party has been pushing for voters who will vote for his Party in particular throughout its history.

Were the move centered on getting DC residents the right to vote in Federal elections, it would be straightforward enough to return the ex-Maryland portion of DC to Maryland (the ex-Virginia portion having already been returned), where they would have full representation. Straightforward, that is, were the Progressive-Democrats not in the way that simple granting of the Federal franchise.
