it has 29% (!) of the likely Democratic electorate as Hispanic... I know the population is accelerating and so on, but that seems so damn high. the racial composition in the poll is 48% white, 29% Hispanic, 14% Asian, and 9% black.
Actually, California as a whole is 35% Hispanic. Around 5-10% of that consists of illegal immigrants, however, and Hispanics are bad at turning out, but that Hispanics lean towards the Democrats cancels that out somewhat. I would guess the Democratic primary electorate will be about 20% Hispanic.
The poll also seems to overestimate Asians and possibly underestimate blacks (who are only 6% of the population but overwhelmingly Democrats and probably more motivated to vote than usual). Still, these demographic issues aren't huge, at least not enough to make a big difference in terms of results.
Edit: I see it was 16% in 2004. Not sure what to make of that, given different circumstances in terms of how important the election was.
Edit2: California was on Super Tuesday in 2004 as well. Kerry had the nomination wrapped up by then, but Super Tuesday still got a fair bit of press.
