John Kasich, the Republican governor of Ohio, has done some surprising things lately. First, he did an end run around his state’s Legislature — controlled by his own party — to proceed with the federally funded expansion of Medicaid that is an important piece of Obamacare. Then, defending his action, he let loose on his political allies, declaring, “I’m concerned about the fact there seems to be a war on the poor. That, if you’re poor, somehow you’re shiftless and lazy.”

Obviously Mr. Kasich isn’t the first to make this observation. But the fact that it’s coming from a Republican in good standing (although maybe not anymore), indeed someone who used to be known as a conservative firebrand, is telling. Republican hostility toward the poor and unfortunate has now reached such a fever pitch that the party doesn’t really stand for anything else — and only willfully blind observers can fail to see that reality.

The big question is why. But, first, let’s talk a bit more about what’s eating the right.

I still sometimes see pundits claiming that the Tea Party movement is basically driven by concerns about budget deficits. That’s delusional. Read the founding rant by Rick Santelli of CNBC: There’s nary a mention of deficits. Instead, it’s a tirade against the possibility that the government might help “losers” avoid foreclosure. Or read transcripts from Rush Limbaugh or other right-wing talk radio hosts. There’s not much about fiscal responsibility, but there’s a lot about how the government is rewarding the lazy and undeserving.

Republicans in leadership positions try to modulate their language a bit, but it’s a matter more of tone than substance. They’re still clearly passionate about making sure that the poor and unlucky get as little help as possible, that — as Representative Paul Ryan, the chairman of the House Budget Committee, put it — the safety net is becoming “a hammock that lulls able-bodied people to lives of dependency and complacency.” And Mr. Ryan’s budget proposals involve savage cuts in safety-net programs such as food stamps and Medicaid.
