Robert Novak, who will be a John Locke Foundation Headliner speaker on July 24, has this to say about U.S. Sen. Elizabeth Dole in his latest column:

Sen. Elizabeth Dole of North Carolina, viewed as one of the most vulnerable incumbent Republican senators seeking re-election in 2008, has made a comeback with successful fund-raising and a boost in approval ratings.

Dole’s private polls put her favorability level at 59 percent, compared with President Bush’s 42 percent. Republican insiders attribute that mostly to her opposing the immigration bill backed by Bush.

Blogger Mickey Kaus takes it further:

Note: That’s not a comeback just among Republican primary voters. It’s a comeback among all voters. … P.S.: Yes, Dole’s obviously trying to scare away challengers by leaking those private polls to Novak. I bet Lindsey Graham wishes he could do that.

I wonder what Sen. Richard Burr’s polls are saying?
