“What they’re really going to need is a conservative, who’s willing to roll back the worst of that party’s abuses. I don’t see any such animal in their party, and I highly doubt that one even exists.”
Could they bring Lieberman back in from the cold, and fake it with him? Or is he too old?
I don't think Lieberman would even accept the offer, if tendered, even though he's the closest thing they have to a real centrist.
He'd be a bad pick because he's simply not inspiring, nor does he seem like much of a leader. I'd say that he's their McCain. It would be an admission of abject failure for them to run him, after having stormed the galaxy with The One Light Worker.
