More numbers trickling out of Public Policy Polling (D) from New Jersey. Today, the firm releases results of potential matchups in the gubernatorial race if Gov. Jon Corzine (D) were replaced as the Democratic nominee. Newark Mayor Corey Booker (D) and U.S. Rep. Frank Pallone (D) fare no better against Chris Christie (R) in the unlikely scenario Democrats did dump their standard bearer, much as they did in the 2002 Senate race.

Here are the outcomes, with the baseline being the actual horserace:

Christie 41 - Booker 33 - Daggett 13
Christie 43 - Pallone 23 - Daggett 15
Christie 44 - Corzine 35 - Daggett 13

Booker is the better known figure of the two potential replacements, with a fav/unfav split of 41/20. Pallone's split was 14/25. There's been no suggestion that Corzine would drop out of the race with less than 50 days left, however. Still, PPP suggests Booker's numbers are "pretty darn impressive" and could be a potential statewide nominee for the party in future elections. Booker took office as Newark mayor in 2006. The firm also says Booker's race would not be a major issue, as he is viewed more favorably among white voters (40 percent) than Corzine (25 percent) or President Obama (37 percent).

The automated telephone survey of 500 voters was conducted from September 11-14, and had a margin of error of +/-4.5 percent. Christie now leads by 7.2 points in the RCP Average.
