I think that's speculation at best. Certainly in the House it was problematic.
President Trump deserves every chance to succeed in advancing his agenda outlined when he ran for President. He knows what he is up against (media, GOPe, etc. - I don't believe that has (or should have) taken him by surprise.
Oh come on.
Put a major defense spending bill in front of the House and LET them try vote it down.
If he had, and and they had, the leftists and the rinos would have been wiped out come next fall.
Instead, sorry to say it, but he listened to the squishy mob around him and caved.
