The executive branch does not hold the power of the purse, and the fact that you can casually use that phrase in reference to the executive branch shows how far we’ve fallen as a country in a decade.
A very sad state of affairs.
At times they don't even cotify their subservience through the usual measures like legislation and committees, except where needed to slap down any roadblocks to the unitary executive.
It doesn't matter how aligned you are with his worldview, how much you vote alongside his wishes, if you aren't 100% loyal to him personally at all times you're politically dead in the Republican party in much of the US.
While Trump's ability to sway normal elections is next to non-existent anymore (see: the vast majority of special elections held since his inauguration where Republicans are getting roflstomped by Democrats), his endorsement still decides Republican primaries because there's still a lot of brainwashed Republican cultists on the Trump train.
My hope is tempered, to say the least.
