Speaker of the House John Boehner says failing to raise the debt limit "…would be a financial disaster, not only for us, but for the worldwide economy." Senator Lindsey Graham (also a prominent Republican) says it would lead to "financial collapse and calamity throughout the world."
So I guess we won't see any Republicans saying, in effect, "If we don't get everything we want — including more tax cuts for the wealthy, more cutbacks on a woman's right to choose and the elimination of social programs we've always hated — we won't vote to raise the debt limit."
Thank goodness they'll all put the general welfare of the worldwide economy ahead of stuff like that.
