At least, they care about their own liberties, without necessarily recognizing that their rights are largely defined by the rights they extend to others. I don't expect many "freedom loving" right-wingers and Tea Partiers to oppose gross Fourth Amendment violations practically required by Arizona's horrendous new anti-immigrant law. But I retain some hope that people who support authoritarian measures directed against others will resist submitting to similar measures themselves.
I find it harder to retain any hope that Barack Obama will be more protective of civil liberty than George W. Bush. I won't linger here describing what has already been documented -- Obama's adoption and extension of Bush/Cheney counter-terrorism policies, from the state secrets rule to the indictment of a whistleblower who exposed gross mismanagement at the NSA, to the assumption of executive authority to order the assassination of an American citizen (the subject of frighteningly little controversy). I'll simply add to the list Obama's decision to join anti-libertarian right-wingers in spuriously condemning the "judicial activism" of Supreme Court decisions defending our rights and liberties. I second Glenn Greenwald's analysis of this, and I wonder why I bother voting.
