I wouldn't call a whole lot of circumstancial evidence as baseless.
"Circumstantial evidence is evidence that relies on an inference to connect it to a conclusion of fact—like a fingerprint at the scene of a crime. By contrast, direct evidence supports the truth of an assertion directly—i.e., without need for any additional evidence or inference.
On its own, circumstantial evidence allows for more than one explanation. Different pieces of circumstantial evidence may be required, so that each corroborates the conclusions drawn from the others. Together, they may more strongly support one particular inference over another. An explanation involving circumstantial evidence becomes more likely once alternative explanations have been ruled out[citation needed].
Circumstantial evidence allows a trier of fact to infer that a fact exists. In criminal law, the inference is made by the trier of fact in order to support the truth of an assertion (of guilt or absence of guilt)."
What the #pizzagate circumstancial evidence are most strongly pointing at is the classic politics infiltrated by a pedocriminal ring hypothesis. The only other inference which hardly come as any challenge to it is that a bunch of people Inside the Beltway are obsess with food to the point of talking about it in contexts that doesn't make any sense.
Here is an example showing that organized pedophilia at high level of governments is a very real possibility, in case you would be tempted to dismiss #pizzagate as fake news on the basis of probabilities:
