Barr can try to deny another Clinton the presidency - this time he could have better luck.
Perhaps. I can see Barr doing "as well" as Paul has done. Supposing Paul wins his primary, he is only opposed by a Libertarian (who probably will drop out now that he is running for re-election), he could endorse Barr. A former Republican, he would have a decent chance of holding together the coalition that has raised so much money for Paul. It's not like he'd win or anything, but Bob Barr would easily better the typical Libertarian showing.
