No argument on Amash; he’s an ass hat, but you need to look into the things that Paul Ryan said and did, as well as Podesta’s emails that clearly refer to Paul Ryan “PR”. Amash does not represent the entire FC and is no threat to the president whatsoever; Paul Ryan is.
Look, Ryan is a known backstaber but he is also the speaker of the house. Your post seems to suggest that Trump can choose not to work with him and still get legislation across. That is simply not true. Trump has no choice but to work with Ryan. His entire legislative agenda will go through Ryan as long as Ryan is the speaker. Expect many more bad bills and pray that the senate has the wisdom to fix them.
