> Just because he's "good" on this issue doesn't change that... You have to deny them victories, even on issues that you support
I understand this argument when it's something like a good stance on education, with bad stances on abortion and the environment. There are lots of people on the left who would share that education stance, and they should be championed instead.
But that's really, really not the case on surveillance. We don't have the luxury of siding with the left and denying the right (or vice-versa). Dianne Feinstein is the Congressional Democrat's standard-bearer on surveillance. We don't want to empower the right, great. But this is a hugely important issue where the left is terrible. So is most of the right - only a handful of figures on each side (especially Wyden, Udall, and Paul) doing anything good.
So what the heck does party discipline look like? Surrendering the entire issue because the Democrats are so profoundly wrong?
