That's Wyden as Wyden, not because he is a Democrat. Some of the strongest proponents of these intelligence authorities, and in many cases the literal authors of bills expanding these powers, have been leading Democrats e.g. Feinstein.

There is no credible version of history where Democrats as a party are not enthusiastic supporters of these surveillance powers. They've been actively complicit the entire time.

Wyden is an aberration. He (unfortunately) does not represent the party on these issues.

The one raising the point. Apparently standing alone amongst otherwise bipartisan support of spying on Americans.

In American politics it seems like all the good ones side democrat, but it's few enough that most of the democrat party still isn't good ones.
