I read a comment on PowerLine that speaks to this thread
if they don't have the votes for a measure, they move on to the next...
(and further paraphrasing):
McConnel & Boehner are [deal makers] who quite often have a go-along2get-along philosophy. These days, the reigning philosophy in DC is bigger government will eventually solve problems (by assimilation, if nothing else), and let's just stand, Buckley-like, athwart shouting "stop!" yet wispering 'as long as it doesn't upset things too much...'
To this mindset, Carly and Cruz are the revolutionaries.... vive la revolucion!
And here is Steven Hayward noting in his PowerLine column:
Republican majority in Congress does not mean there is a conservative majority
Noting some GOP accomplishments, and quoting Charles Howard McIlwain’s Constitutionalism Ancient and Modern:
A constitutional government will always be a weak government when compared with an arbitrary one. There will be many desirable things, as well as undesirable, which are easy for a despotism but impossible elsewhere. Constitutionalism suffers from the defects inherent in its own merits.
