The House is back to work this week, since Speaker Kevin McCarthy once again capitulated to a dozen extremist lawmakers who had shut the place down last week over a varied list of grievances. They eventually decided that their protest was centered on government spending and the deal McCarthy cut with President Joe Biden to avoid sending the nation into default. So that’s where McCarthy caved: He told them they could have the dramatic cuts they had insisted on in return for avoiding economic catastrophe, and then he reneged on the debt ceiling agreement.
