Take a longr view.
THe impoundment power must be restored simply because it is what the constitution had previously brought forth and so does convention.Even if TRump does not succeed, maybe the next presidet will. It has become a necessity.
As to those with TDR, they all will eventually be de-elected or they will die of their own TDR invoked exploding heads or sink into insanity.
How can anyone with TDR work as a representative in any capacity. They cannot.Soon they will all die off or disappear.
