More seriously: no data has been released to indicate that their surveillance tactics are useful. If they want to convince me, as a voter, to continue supporting those tactics, then they need to convince me.
They have other options, of course; if they can convince enough of the other 300 million people, then my single vote against them doesn't matter. It only matters when joined by many who agree with me. But there are a lot of people who do agree with me.
