We had a Republican majority house and senate for two of those years, so I would look there for a failure of Conservative policies. The scumbags like to promise Tea Party/MAGA when they're running, but as soon as the voting stops, the lobbyist bucks commence, and amnesia sets in.
Remember when Trump was president and Republicans had the majority in the Senate and the House? Remember when Paul Ryan was the Speaker? Remember when Paul Ryan and Mitch McConnell prevented Trump from building the wall?
Is that the kind of not delivering the Wall Street Journal/Fox News/Murdochs are talking about?
but precious few supported him.
