On Fox News Sunday, John McCain just said that he would veto any bill which didn't include "a straight up-or-down vote on the issues" (in reference to the one time he voted to raise the minimum wage - it was a part of a war-funding bill). It seems incredibly damaging to place a restriction on the construction of legislation that essentially says you're going to veto any bill which combines multiple issues into a single vote or a few votes. It's a common legislative practice for a variety of reasons, not the least of which is to combine issues to promote compromise and that bipartisan shit people seem to love so much, and/or force votes on issues that wouldn't otherwise get a hearing..
The idea that the President would place a flat denial on any bill which combined multiple issues is an act that's pretty damn certain to increase gridlock in Washington and slow down the mechanism of government to crippling levels. Smooth move, Johnny Mac.
