The reason? Any bill that seeks to amend the Constitution requires a two-thirds vote in the House and Senate. The Boehner bill would raise the debt-ceiling in two stages and make the second stage, around six months from now, contingent on passage of the amendment-- basically requiring a supermajority to approve the increase.
Sen. Richard Durbin (D-Ill.), the assistant majority leader, called tying a balanced-budget amendment vote to the debt-ceiling “outrageous.” And Sen. Charles Schumer of New York, said it was “an absurd proposition.”
“Speaker Boehner should just give it up,” Schumer said. “He throws piece after piece after piece of red meat to the right wing lion that seems to dominate his caucus. It’s time he tame that lion for the good of the country.”
