Not sure on the exact margins, but the new LA Times polls of competitive CA House districts showed the gas tax repeal initiative failing pretty badly:
It's hard to see how that passes if it's only getting 1/3rd of the vote in Walters' district. It was supposed to be cat nip for Orange County voters. I suppose it doesn't help that the No camp is outspending Yes 18 to 1.
How it looks per district (Yes/No/Undecided):
CA-10: 30 - 41 - 29
CA-22: 40 - 37 - 23
CA-25: 37 - 39 - 24
CA-39: 40 - 37 - 23
CA-45: 33 - 44 - 23
CA-48: 33 - 45 - 22
CA-49: 32 - 48 - 20
CA-50: 44 - 37 - 19
