From a civil liberties perspective, I am not comforted by Obama's capitulations on FISA and the PATRIOT Act, and neither am I comforted by his choice of one of the fiercest enemies of privacy in Congress as his running mate. Biden bragged that he "wrote the PATRIOT Act", and he was the originator of the office of the Drug Czar.
You may think Obama is better than McCain, and that is your right, but lets have an honest view of his actions in mind when we make that choice.
