And let's look at those polls. President Trump's approval rating is indeed historically low for a new president and hovering at the 40-50 percent range, according to an aggregate of polls by FiveThirtyEight.com. But the key word in the previous sentence is "historically." The need to keep your approval ratings much higher now is just that; history. Remember that candidate Trump consistently posed disapproval ratings in the 60-70 percent range during the campaign. By contrast, his 50-60 percent disapproval rating now is a marked improvement. And that's not a joke. Could President Trump be the first president in generations to leave office with higher approval ratings then when he came in? Considering the low numbers he had on day one, he has the best shot.
But if you need more evidence of the alternative political realities in America, just look at what happened this weekend. Not only did President Trump refuse to attend the White House Correspondents Dinner and get roasted like his predecessors, he held a massive cheerleading rally for himself in Pennsylvania at the same time. President Trump probably wants the established media's approval as much as anyone, but the key point is he can survive without it.
None of this means President Trump is doing a great job, or at least doing as good a job as he and his cabinet members say he's been doing so far. What it does mean is that he's going to survive and succeed on his own terms no matter what the old rules and the establishment judges say.
Because the establishment remains under furious attack. The old rules aren't just obsolete for President Trump, but for all of Congress as well. Even House Democratic Leader Nancy Pelosi is now going to be challenged by a Bernie Sanders supporter in the primaries in her supposedly super-safe district. It is indeed a political world turned upside down.
But so far, not enough people in Washington seem to have heard that message. The same self-appointed judges of presidents and political success who got their election predictions so wrong are also using these first 100 days as their "proof" for why the Trump presidency is already and will continue to be a failure. They keep operating as if the most serious change is the fact that Donald Trump won the electoral college, as opposed to the serious change in voter sentiment that made that happen.
At some point they may get the message that their rules and proofs don't matter anymore. But either way, President Trump is going to keep on following his own drummer. And the rules have changed enough to enable him to do so indefinitely.
