NEWSWEEK:

It’s hard to say which is worse news for Republicans: that George W. Bush now has the worst approval rating of an American president in a generation, or that he seems to be dragging every ’08 Republican presidential candidate down with him. But According to the new NEWSWEEK Poll, the public’s approval of Bush has sunk to 28 percent, an all-time low for this president in our poll[..].

While the poll has some high marks for Clinton, it's not all good news. Though the New York senator and former first lady aims to project an aura of inevitability that she will win the Democratic nomination, Obama beats the leading Republicans by larger margins than any other Democrat: besting Giuliani 50 to 43 percent, among registered voters; beating McCain 52 to 39 percent, and defeating Romney 58 percent to 29 percent.

Like Obama, Edwards defeats the Republicans by larger margins than Clinton does: the former Democratic vice-presidential nominee outdistances Giuliani by six points, McCain by 10 and Romney by 37, the largest lead in any of the head-to-head matchups. Meanwhile, Sen. Clinton wins 49 percent to 46 percent against Giuliani, well within the poll's margin of error; 50 to 44 against McCain; and 57 to 35 against Romney.
