NRSC did a poll in OK showing Bush +20 and Coburn +12.http://www.clubforgrowth.org/blog/images/04-08-04%20OK%20senate%20race.pdf
The Public Poliy Institute of CA did a poll showing Kerry +16 and Boxer +17.http://www.ppic.org/content/pubs/S_804MBCAGS.pdf
Both documents have favorablility questions and the like, but the CA document is pretty comprehensive over statewide questions. It has some ballot measures and Arnold's fav numbers. Arnold has 63% favorable, while Bush is at 40%.
