It's not clear to me how you are identifying "public" anxiety, as opposed to the anxiety of Washington. We can observe the latter in the behavior of Congress, e.g. The former is unclear. In any case, let's go with "anxiety". Why is there sudden anxiety? Why should we worry about Pizzagate now while we didn't worry about similar things two years ago? The answer is simple: Trump was elected. He is not alone; there is a…
>Why is there sudden anxiety? Why should we worry about Pizzagate now while we didn't worry about similar things two years ago? Because Pizzagate, along with other fake news, misinformation and slander campaigns, appear to have contributed in a nontrivial way to Trump's election, and all of them are by definition complete and utter bullshit. We should worry when obvious nonsense takes precedence in our political disc…

You suggest it contributed meaningfully to Trump's victory; I don't believe that. I think Trump won because he coopted a largely leftist critique of capitalism that resonated with Americans. This critique was also available in Sanders' campaign, which was marginalized in favor of Clinton's "things are fine, more of the same" message.
This is exactly what is happening everywhere else; Macron lost because he wanted to maintain the "there is no problem, we don't need to reform our ideas" pose. The result is people vote for the only folks offering change, even ersatz change: the right.
The appearance of these rightwing movements after the crash of 2008 is also not a coincidence. Neoliberalism is in crisis, serious crisis that goes well beyond a mere confusion over facts. People are looking for alternative facts in the first place because they are dissatisfied. The first, easiest place to find those answers is the fascist right.
So long as neoliberals continue to deny this crisis, continue to pretend their policies are good and should be popular, and continue to incorrectly blame "fake news" or "the Russians" for their woes, they will continue to lose elections, and real power, to a dangerous creeping fascism.
