We are in a discussion thread talking about an instance where the US government voted to essentially remove all privacy protections for Americans, and it was completely down party lines. Every Democrat voted against it. Every single one. Nearly every single Republican voted for it except for a couple with some principles -- e.g. Paul, who most Republican politicians would love to get rid of and mostly ignore.
I don't really like Obama admin views on domestic spying either, but government spying for "national security" reasons with FISA warrants is quite far away from "free-for-all, all of your most personal and private history is now available to the highest bidder". While I disagree with both, I can see the nuance there, and so can the 48 Democratic and Independent senators.
