A tax chairman voting against the bills

What stands out is how many of his departures are votes against bills at final passage rather than amendment votes. Five separate measures passed the Senate with his conference behind them and with him opposed — among them a benefits bill, a continuing appropriations measure and a further spending bill.

Two run the other way: a bill he supported at passage against his party, and a foreign aid supplemental he voted to pass. Alongside these are the usual amendment votes in both directions.

A member with this much control over what the committee produces, voting against what the floor produces, is drawing a line between the two.
