Montgomery County Councilman Marc Elrich isn’t running for governor. Really.

That would be former Republican Gov. Bob Ehrlich, not exactly the Democratic councilman’s political doppelganger.

But a speaker during a council meeting Monday dared to call him Ehrlich — apparently an all-too-common mistake — forcing him to grumble, “You’re so cruel.”

But there is one perk: free publicity.

“People would tell me all the time they liked my bumper stickers even though I didn’t have any,” he told The Washington Examiner. “I guess that’s a plus.”
