Obama leading Clinton in 3 different CA Polls

[Alcon]

The majority of that 30% will break for Clinton; my prediction.

On what basis?

Clinton has been the one losing in the polls, and undecideds rarely "wobble" back to their original candidate when there is this sort of momentum.

Then again, if those all are very marginal Clinton supporters considering Obama...but that would be a rare occurrence not really supported in other polls.
