Thomas Sowell‘s latest column at National Review Online focuses on the important role of voter turnout in determining control of the next Congress.

Some of us this election year don’t even want to say the words “Clinton” or “Trump” — and with good reason. However, there is one word that we should keep in mind: “turnout.”

If we sit home in disgust on Election Day, we forfeit the right — and the duty — to elect a Congress that can keep either of these dangerous people from doing permanent damage to this country and to the future of this generation — and generations yet unborn.

Control of Congress has probably never mattered more than in this election, simply because of two out-of-control people, one of whom is going to become president of the United States.

We need a Congress that can block dangerous legislative proposals coming from the White House, and block dangerous nominees to the federal courts, including especially the Supreme Court. More than that, we need a Congress that can remove a dangerous president who ignores the law and commits impeachable offenses. Any Congress theoretically can do so, since the House of Representatives has the power to impeach and the Senate then votes on whether to remove the president from office.

However, as we have seen over the past seven years, that theoretical power means nothing, if neither House of Congress has the incentives and the guts to use the power they have.
