The simple answer is that Republicans should be hell bent to remove him as Speaker.
If those Republicans who "should" vote him out actually had any decency or honor they would remove him now.
They KNOW what the plan is and they can stop it.
But they won't. Because they support it...they just don't want to take the heat for it.
Apparently there's not ONE Republican in the House who is actually committed to their election promises. Otherwise one would throw down the gauntlet and Challenge for the Gavel.
AT LEAST make a big show of it, even if he loses. Shine the light.
