Not the only reason, but certainly a good one for conservatives.

Fundamentally conservatives reject the notion the federal government should be involved in anything other than military defense. It is an idiot-ological position which is more than just difficult to convey or sell to the "base", who for the most part are simply ignorant of and lack the understanding of the abstraction.

Thus the arguments revolved around the non-existent "death panels", etc. The current arguments are all single word criticisms (collapse, death spiral, etc) which have mass appeal for people who do not want to or are incapable of looking beneath the hood.

What these conservatives are trying to sell to their base is, if you have a job and are getting insurance then your premiums will go down. And if you are wealthy your taxes will go down. It is a self centered plan which appeals to conservatives in general.

From an idiot-ological perspective, they will remove the federal government as much as is possible, which will appeal to the wonks. These guys could care less if poor folks get covered i.e. poor people should have been born "rich".

This is one of the Big Four, repeal (but not necessarily replace) ACA, the Great Wall of Trump, and tax reform (including deregulation), and the Muslim Ban. These are not going away, even if there are roadblocks.



ignorance is the enemy
without equality there is no liberty
America can survive bad policy, but not destruction of our Democratic institutions
