I feel it was started a lot earlier than that. Late 80s early 90s saw the proliferation of "news talk" radio popular amongst Working Joes and the 1996 Telecommunications Act signed by Clinton essentially paid for by Fairness And Accuracy In Reporting (FAIR) solidified corporate monopoly messaging and the freedom to hear Feel Like Making Love a brazilian times.
This is just such an oft-repeated undefined criticism. Obama was pretty prominent last campaign. That guy is a bad communicator? Was Walz? Compared to last year's rambling, people leaving early Trump rallies?
You're illustrating my point. The Democrat Executive checks it's own supposedly dominant position over the Legislative, while the GOP publishes it's own rationalizing of the unitary Executive, and as we're witnessing, carries it out.
Again, had the bigger problem been an Executive Branch growing in power at the expense of the Legislative rather than the actual bigger problem, the Republican Party, Obama would have gotten his Supreme Court nominee.
This "no one is innocent" notion is the binary false equivalency MAGA uses to rationalize it's deliberately destructive, zero sum pursuit of self-interest.
It was facetious. There's virtually no way any Trump voter can claim they didn't vote for a candidate that campaigned on tariffs. It wasn't some hidden agenda. The point being there's an significant chunk of the voting public that will believe what they want to believe regardless of what a candidate says or how they say it.
