From the LAT:
Former New York Mayor Rudolph W. Giuliani holds first place in the survey, with support from 27% of the Republicans and independents who said they plan to vote in the party's 2008 primaries.
But Thompson, an actor who played a prosecutor on NBC's "Law & Order," runs just behind, with 21%. Indications are he will join the race within the next month.
From Rasmussen comes this extra tidbit of information:
A week ago, Giuliani had a six percentage point lead over Thompson, 23% to 17%.
Now it's tied at 24%. And he hasn't even spent a dime.
