The number of random people who ask me about NSA spying now vs. 6 months ago is huge.
The DEA partnership basically won over minorities, drug people, young people.
You could probably find ways to make this an anti-immigrant issue in general (spying on foreigners; obviously if you're Muslim or brown, but maybe it could somehow extend to Chinese immigrants too?)
Tech people hate it naturally. Business people (other than defense contractors) hate it because it makes doing business harder, particularly if you're doing business with Europe or other international business.
This abuse of Greenwald's lover might win over gay people.
Gun people were already super suspicious of the government since Sandy Hook w.r.t. registry and confiscation (honestly for the entire Obama administration, and even during Bush, and definitely during Clinton, too, but more so now)
Right wing people are suspicious due to IRS and general hatred of Obama. "NSA shares records with IRS" would be a great extension to the story, but even lawful IRS subpoena of electronic records supports the case for strong crypto under the control of the end user.
All we need is for NSA records to be used against Christians (pro life groups? I'm finding it hard to find ways NSA spying is specifically anti mainstream Christians) to essentially have 80% of people on the side of freedom, each for his own reason and maybe totally different from the others.
The only people left on the other side are die-hard militarists, defense contractors, and the political class, or people who are irrationally putting hypothetical safety over even their own liberty (I'd expect people to sacrifice unused liberty or the liberty of other people for their own hypothetical safety, always).
