While I'm not really a Hillary supporter, for a guy who's constantly accusing others of BDS when Bush is questioned or criticized, you sure do seem to suffer from the alternate affliction of CDS (I suppose like many other right-wingers do).

<snark> Heck, you'd almost think people like you would want the Clintons back in the White House to a) have something to gripe about and b) to try to impeach Hillary to see if you'd succeed where you managed to fail before. </snark>

1. He's harder to control. Campaign staff and the candidate usually can gently or otherwise coax the future first-Lady into saying exactly what she's told she needs to say, and moderating any of the more extreme opinions she might have. Though lately potential first-Ladies are very capable proffesionals in their own right, they aren't usually politicians, so they are easier to manage. Bill on the otherhand can't be sat down and told “now be a good boy, smile and don't say anything funny dear.” I doubt he'd stand for it.
2. Unlike others, he can't just hide behind “it's my wife that's the candidate, not me” in discussions on issues. Other spouses get something of a pass if they make mistakes or say silly things in response to issue questions, or don't get asked those questions at all. Bill Clinton was once president, he will not get any passes for saying inappropriate things on the issues.
3. He's been in the most powerful position on the planet. That has to give you a sense of “I speak, others listen”. Yes he knows the game, but I bet you sometimes the sheer confidence (or arrogance) that ANY president has, must shine through and he simply will not shut up.

Bill as a presidents spouse: I think he would be a much greater asset than a problem. He is a powerhouse all his own. He could be a tremendous boost to his wifes administration, pulling in his old contacts and favors. Sure he'd terrorize the maids at the White House, but overall, I think he'd be very good. I'm not voting Hillary because SHE'S the candidate, not her husband, and I don't trust her one bit, but Bill is a definate point in her favor.
