Democratic Leader Rep. Nancy Pelosi, D-Calif., in the midst of fending off a coup to derail her return to the House speakership, is proposing a series of rules changes that could kneecap liberals from pursuing a bold agenda in the new Congress.

Among the many proposed rules changes the incoming majority plans to make in a draft document obtained by the Washington Post, is one backed by Pelosi and Rep. Richard Neil, D-Mass., ranking member of the House Ways and Means Committee, that would “Require a three-fifths supermajority to raise individual income taxes on the lowest-earning 80% of taxpayers.”

The proposed changes also hint at restoring some sort of “reasonable rule” aimed at making sure legislation is paid for, though there isn’t much elaboration.

Liberals are already raising alarms about the proposal, and from their perspective, this is understandable.
