The problem is, the activists who get the job done on the Left aren't moderate. She came out co-sponsering a bill to make flag burning a federal offense, too. Can you think of anything more heinous to the Daily Kos folks during a time when "civil liberties" are the watchword?
What she fails to take into consideration is that she has to get through the primaries and get the nomination if she is going to run for president. Courting Rupert Murdoch isn't getting it. She finished fifth in the Daily Kos poll with 2% of the vote. Granted, that's not your average Dem voter, but they are the ones that fight on the front line.
So, she's gaining no more than a handful of moderate votes, and stabbing her activist Lefties in the back. She thinks the fix is in for the primaries, and that the Left won't find a Perot to bleed votes. I think that is a pretty irresponsible assumption, frankly. Traitors never find a home on either side, and betraying her friends for political capital isn't going to gain her respect from Republicans.
