“the rule” is the cloture of the House. Like the senators that vote to “proceed to debate” and then vote against the bill, congressmen vote “for the rule” and then against the bill, when they know it will pass.
They get to have it both ways. They get the legislation they want but can tell their constituents that they voted against it.
But we’re on to their game!
Remember when they used to rise and always say; Permission to revise and extend my remarks, even to include extraneous material.
In other words no matter what I say, I can change it all in the written record.
