As we've discussed earlier
, McCain may end up playing a very important role in the tax cut debate -- something that has as yet not gotten much attention. Tonight he's beginning to tip his hand.
On CNN this evening, using roundabout language, he signaled his problems with the Bush plan and added an important detail. He said that the issue for him was less the size of the Bush tax cut than whom it went to. That's striking, because if anything questioning the progressivity of the cut is the more leftish ground from which to oppose the cut.
And that has lotsa implications for the coming months.
