The Senate voted to extend the child tax credit to people who don’t pay income taxes. The only holdouts were Oklahoma’s Republican senators, Don Nickles and Jim Inhofe. The media and the Democrats were pounding Republicans over the issue, but I doubt that most voters were paying much attention. To the extent that the Republicans were being hurt by the charge that they had stiffed working people, this cave-in makes the problem worse: Now they look as though they were trying to pull something and got caught. The House Republicans are not planning to go along with this, and they’re right.
