MOST PEOPLE who saw House Speaker John Boehner’s fiery speech to the nation on Monday night assumed he had capitulated to his party’s far-right fringe. But not even that sufficed; Boehner spent much of yesterday scrambling to convince ultra-conservative House Republicans that his debt-reduction proposal goes far enough. It turns out many Tea Party adherents can’t even bring themselves to accept the speaker’s plan for $1.2 billion in cuts to discretionary spending alone, a gutting of the programs that constitute the ordinary business of government - education, transportation, energy, environmental protection - without any tax increase at all. It would also force another debt-ceiling vote in six months, in the midst of the 2012 campaign, which would give the Tea Party a whole new chance to make its demands.
