Some Republicans appear to be softening what was once a hard stance on their no-taxes pledge as the end-of-the-year deadline on the so-called “fiscal cliff” approaches. But it’s not clear how far they would go – if they would raise rates on the wealthiest, as President Obama wants, or if they are simply willing to go along with eliminating some loopholes and deductions to raise revenue. And those who have been outspoken on the topic thus far are not seen as the key players in the ongoing negotiations.
