I think this misrepresents the split.
Trump's views on privacy are obvious and awful, yes - he has Sessions as AG.
But Dianne Feinstein is one of the fiercest surveillance advocates in Congress. Hillary Clinton had vastly more support from intelligence agencies than Trump did, and refused to condemn what was described in the Snowden releases.
Meanwhile, Rand Paul ended bulk phone record collection for a few hours in 2015, defying much of both parties to do so. He filibustered over drone strikes, and promised to restrict NSA searches if he was elected.
There's a lot to dislike about Rand Paul, and libertarians aren't the only people opposing surveillance - Bernie Sanders made similar promises from the far opposite end of the spectrum.
But I think framing this as "bad under Democrats, hopeless under Republicans" makes it harder to address the problem. The mainstream of both parties are similarly awful, even if the Democrats talk a bit more softly about it, while the fringes of both parties are often strong surveillance opponents.
