If you’ve lived in D.C. for any amount of time, you’ve lived through your share of protests big and small. Just pick a cause, any cause, and we can guarantee you that sooner or later its true believers will find their way to our nation’s capital, to stand on the National Mall, wreak havoc on downtown traffic, clog our metrorail system, fill up our hotels, and spend money in our shops, food courts and restaurants. (OK, so protests aren’t all bad.)

Well, get ready for another one. Supporters of displays of the Ten Commandments in America’s courthouses are coming to Washington. On March 1-2, Faith in Action — which bills itself as a “Christian outreach whose mission is to reintroduce the Word of God into the public debate surrounding legislation and policy matters” — is sponsoring a candlelight prayer vigil, news conference and march to the Supreme Court in support of the public display of the Ten Commandments, as the high court hears arguments for and against such displays at the Texas state capitol and a Kentucky courthouse.

Whether enough supporters will show up to stop traffic, clog metrorail stations, or fill hotels and restaurants to overflowing is anybody’s guess. We just want to forewarn our fellow DCists of the next protest to hit down. Of course we hope (or is that pray?) for the best.
