Republicans might be relieved after pushing their health care plan through the House Thursday, but Democrats issued them a warning: That won’t last.

After the vote, some House Democrats waved farewell to their GOP colleagues and then started singing, “Na na na na, hey, hey, hey, goodbye.”

The reason for the chant? Democrats believe the health care bill — which Minority Leader Nancy Pelosi said will strip coverage from millions — will backfire on House Republicans with voters when they come up for re-election next year.
