Seems there are those who think Bill is a detriment to Hillary's campaign.

"Mr. Clinton’s temper has been an issue for him as long as he has been in public life. But it has played an unusual role during the current campaign, his face turning red in public nearly every week, often making headlines as he defends his wife and injects himself, whether or not intentionally, into her race in sometimes distracting ways.
Some Clinton advisers say the campaign is trying to rein him in somewhat, so that his outbursts become less of a factor to reporters, but his flashes of anger only seem to be growing. Last week, for instance, a clearly agitated Mr. Clinton told Dartmouth students that it was a “fairy tale†for Mr. Obama to contend that he had been consistently against the war in Iraq. And in December he said that voters supporting Mr. Obama were willing to “roll the dice†on the presidency.
“The bottom line is, his outbursts don’t help the campaign,†said James A. Thurber of American University, an analyst of the presidency and Congress. “They become an issue, and it can grow into a real problem. I think the campaign is worried about him right now.â€
