I don't think he wonders about anything at all. He knows (and is wrong).

Because people read the ending of "the selective publication of White House visitor logs online" as something menacing?

Especially if it was "selective" to begin with...

Increasingly? Weren't most of his supporters somewhat skeptical from the start?

His approval rating was highest his first week as president:

That's because he fired missiles in Syria and detonated the MOAB in Afghanistan. Whenever a president commits an act of war against a publicly perceived threat, their ratings get a temporary boost.

Neither of these things were done the first week of his presidency.. He started in January, it's now April, which is when these events happened...
