I don't understand why you guys think likely voters is the only one that matters in May. Likely voters could easily change by November. Granted Likely voters is all that matters in November, but in May I believe registered voters definitely matters as well.
In the latest Gallup Poll Kerry leads by 2 in both anyway. The last time their was a 5 point difference in registered and likely, and I think that was an abstraction. The registered and likley voters may see some difference, but I doubt that is more than 1 or 2%. Bush going up in registered and down in likley was probably just the poll correcting itself out because of the difference the poll had last time
