With the federal government shutdown looking to drag on for a while, an array of public opinion polls show overwhelming opposition to the Republicans’ “strategy” of choking off discretionary spending programs to block implementation of the Affordable Care Act.One of those national polls, by Quinnipiac, reveals the breadth of the opposition. Seventy-two percent of Americans are against it. Not surprisingly, 90 percent of Democrats frown at it. Independents? Seventy-four percent. Even Republicans only narrowly back the move: 49 percent to 44 percent.One wonders why the 44 percent of the GOP can’t buy the 49 percent a beer and have a heart-to-heart about the folly of committing bad public policy and of shoving the U.S. into the territory of global dunderhead.Because the shutdown, not to put too fine a point on it, is a colossus of stupidity.But I’ll get to that in a few paragraphs. That, and an even greater threat to our livelihoods: that the U.S. will crack the debt ceiling in less than two weeks.First, an important point needs to be made: While the Republicans are feeling the heat of overwhelming public disapproval, that doesn’t necessarily mean the extremists among them will cave to pressure.
