More over the flip. 

There is much more movement in the Republican poll than the Democratic one, due to the emergence of Fred Thompson as a likely contender.  He is in the running here in California and if he does not stumble out of the gates he should get another bump from his announcement.  And this is interesting.

Among Conservatives, Thompson is up 12 points month-on month, and has gone from 4th place to 1st. There is volatility among Hispanics, who make up 17% of likely Republican Primary voters in SurveyUSA's turnout model: Giuliani has lost 23 points month-on-month, down from 46% to today 23%. Thompson's support among Hispanics is up 5 fold, from 5% to 24%. Margin of Sampling Error is high for this small subgroup, but the movement is striking nonetheless.

On the Democratic side, Clinton is holding steading on to a substantial lead.  There has been little that has occurred over the last month to shake up the numbers.  This poll was conducted prior to the debate on Sunday.
