while the Dems use the moral failings of DJT as the primary attack against any policy he proposes.
I'm not sure what you're reading/hearing, but I see plenty of counter-arguments to Trump's proposal that are policy-based.
There are plenty of policy counter-arguments to DJT's proposals, but they often get lost in the drumbeat of social criticism/outrage over the man himself. Which is a good argument to make, but when every response is "he's unfit!" and rejection seems to come from abhorence to the man instead of rejection of the policy it reinforces this "us-vs-them" mentality which dominates our politics.
Example:
News - DJT announces a new controversal executive action
Dem response: Trump knows nothing and doesn't bother to learn, he just made this to satisfy his shrinking base, this will only help the wealthy and hurt us overall.
That's how I see almost every action he does play out in the media. Note that only 1 of the 3 knee-jerk responses in that hypothetical had anything to do with the policy itself, and while there *is* analysis on the policy, much of the outrage is still focused on DJT and his lack of knowledge/fitness/compassion.
It certainly occurs the other way, too
News - Mueller indicts a new person and subpoenas someone else
GOP response - Mueller is out-of-bounds! he hired people who have a political opinion so its all biased! These latest charges have nothing to do with the administration!
