Wow. First, this is the LA Times, which is like a radioactive hotbed of anti-Bush sentiment. They are actually worse than the NYT or the Palm Beach Post, if that can be believed.
Secondly, this is a poll of Registered Voters. That's like taking a poll of the cast of Dawn of the Dead, or trying to count fire hydrants in Chicago. The likely voters count could be another point or two in our favor.
Right now, Kerry still leads in EV's overall, and by a sizable margin. However, as the horserace numbers go Bush's way, expect the marginal Kerry's to move to Tossup, thence to marginal Bush in September. Some could be solid Bush by the time October rolls around, especially after the World Series concludes.
Be Seeing You,
