Both sides are run by the same groups. Trump, as an outsider, forced them to reveal it far more than they preferred to protect the bigger grifts. Things like Obamacare was suddenly defended by those that literally ran on dismantling it. Trump not wanting to jump balls first into new wars also disturbed them. And apparently illegals are absolutely necessary for whatever agenda they have since it's extremely unpopular yet both sides keep pushing for more of it.
