"Hillary went into free fall," he writes in Tuesday's New York Post. "Her favorability dropped to 44 percent that February, and to an all-time low of 39 percent in March."

So, what accounts for the dramatic improvement in Hillary's numbers?

Morris says his former client can thank the GOP.

"Hillary's move to the center — including her frequent association, in public, with the likes of Newt Gingrich, Bill Frist and Rick Santorum — is clearly paying dividends."

"It is also likely that Bill Clinton's constant appearances with President Bush Sr. and his highly visible efforts for the tsunami victims are helping rehabilitate his wife's image."

Detoxifying Mr. Clinton's image is a key element in the former first couple's campaign to reclaim the White House. And with Bush family members now referring to the ex-president as "Bubba", "Bro" and "Son," the Clintons' upcoming visit to Kennebunkport is sure to sound like a family affair.

Having her husband become an honorary Bushie has paid off big for Bill and Hill, says Morris:

"In the Fox News poll, 38 percent of voters, including the vast bulk of Democrats, said that they would be 'enthusiastic' about seeing Bill return to the White House as 'first husband.'"

Before the Clintons sway any more of the public, he advises:

"President Bush needs to get his father to pull back on his public bobsey-twins identification with Bill and Republicans need to let Gingrich et al. know of their displeasure with his new found best-buddy relationship with Hillary."
