It's clear where John McCain stands:
Apparently, McCain not only supports Bush's dead-end policy, he's willing to lie about the Constitution in order to get it done.
Webb points out the passage in question on the Constitution, but for the sake of the readers, here is the exact language from Article 1, Section 8:
The Congress shall have Power to...make Rules for the Government and Regulation of the land and naval Forces;
Pretty darn cut and dry, if you ask me.
But even more impressive is what Webb says when the CNN anchor asks about Bush's veto threat:
Let's see if he dares. And the same goes for the Republicans in the Senate. If they really want to filibuster this, let them be on record as obstructing Senate business for hours and hours and hours just to make sure the troops don't get longer leaves of absence. Let them filibuster, Senator Reid. Make it hurt.
