If you mean left-leaning is increased security everywhere, with ID's required for everything, the Govt. being able to spy on you without a warrant in such as way that you will never even know you have been spied upon, ad cameras at every intersection to give you a ticket automatically even if you are not driving the damned car, and every scrap of paper dealing with policy being classified ultra-secret, well, then that is what is happening.
The worst abuses have happened during the Juniorbush years, but it will take a major effort to rescind all the Homeland Security and confidentiality crap. I think the Democrats will be better at this than the Republicans, but I doubt that anyone will restore our freedoms to a pre-911 situation.
The right wing USED to be in favor of personal liberties, and increased transparency in govt., but no more .
