Polls in July

July is a particularly stupid time to be paying much attention to national polling of the presidential election. After all, Michael Dukakis was up by seventeen points in July. But in case you needed more evidence, here are four polls released in the last 24 hours:

Obama (D) 51%, McCain (R) 39% (Research 2000)
Obama (D) 48%, McCain (R) 40% (Gallup)
Obama (D) 48%, McCain (R) 45% (Rasmussen)
McCain (R) 49%, Obama (D) 45% (USA Today/Gallup)

Now that last poll has been filtered through a pretty questionable "likely voter" model (Obama is up 47-44 among registered voters, for a seven point swing between RV and LV). But still, what possible rational reaction can you have to these numbers other than to shrug your shoulders and pray for November to come soon?
