I think Edwards will be a formidable candidate. Who cares whether or not he is a trial lawyer? I have not heard anyone say what makes a trial lawyer bad except that they are supposedly "liberal."
Bush and Cheney are oil men. That has to be below trial lawyer. Nonetheless, I think Edwards would do a great job as president. I am going to put at least my early support behind him, and then see how the primaries turn out.
Sen. Clinton is probably as hard headed as Pres. Bush, and as far as Sen. Obama, I think he would be a great president as well, but he may need to wait a few more years until he gets some more experience. Though I don't blame him for striking while the iron is hot.
I would vote for any of the 3 mentioned above, but for now I will support Edwards.
