The risibly small bounce for Obama has now disappeared, and actually he now polls below where he was in late May and has returned to the level of support he had about one month ago.  That’s not surprising, and I expect we will see blips of movement for both candidates throughout the summer.  The race will likely remain very close unless and until one of the major candidates implodes, and the movement of undecided voters (7%) to one or the other will come fairly late as it usually does.  If the 8% “neither” figure is right, that opens up a larger field than usual to the third party candidates and holds out the prospect of multiple third party candidates gaining better than 1% of the vote, which is quite rare.
