candidate X's position on section 702 would leave the US open to terrorist attack, Senator Y supports keeping Americans safe"

Which is one of the reasons why most of Europe (not counting UK here as it has no concept of written constitution) have the right to privacy of correspondence as a constitutional right. The ones that do not (once again except UK) have a law to that effect. The chapter 23.2 from the RF constitution I quoted earlier is a cut-n-paste+translate from the German one (if memory serves me right).

USA has NO right to privacy of correspondence period. Neither in law, nor in constitution. There is a patchwork of precedent derived from litigating correspondence related cases on 4th amendment grounds, but they do not make up a law. As a result, using 9/11 as a precedent Mr Shrub and Co have successfully pushed into production a system which would make Stazi proud (*).

(*)_{No comment on UK. It is pointless to comment when a country is competing with Saudi Arabia to be the last country in the world to have a written constitution and the concept of fundamental rights.}
