Just for the record, this sentence from Gail Colllins’s op-ed yesterday is wrong:

Witness Obama and Clinton at the debate, racing away from gun control as if they were a pair of greyhounds, forswearing middle-class tax cuts as if they were George H.W. Bush.

Actually, they ruled out middle-class tax increases. As her own newspaper reported, “Mrs. Clinton and Mr. Obama said they would not raise taxes on middle class Americans — those making less than $200,000 to $250,000 a year.”

Update 4/18 2:56 PM — Commenter Dave raises another issue for Times copy-editors:

I never knew that greyhounds were such strong opponents of gun control.

Update 4/19 2:35 PM: Collins corrected the error in today’s column.
