Left and right are increasingly meaningless labels. These days it is more pro-establishment vs anti-establishment.

For example, the most vocal people on privacy are an amalgam of independent thinkers on the "left" (The Guardian, etc) and independent thinkers on the "right" (Ron Paul, etc.)

While the "leftist" Hillary Clinton calls Snowden a traitor (so do a lot of "right"-wing people, too).

Although Britain's left wing party, Labour, is pro surveillance, even it seems under Corbyn, who is himself a target.
