These polls are insane!

[NHPolitico]

Gallup has Kerry up 55 - 43.

Over the same time Rassmussen has Bush up 48 - 43 with a surge over the last couple of days.

Zogby's poll has Kerry ahead in the blue states by only 1, and Bush up comfortably in the red states 51 - 39. (this done 12th - 16th)

What the hell is going on here?  It is either:
1) a conspiracy to drive us political junkies cukoo
2) one or all of these polls are garbage
3) we have entered some political campaign twighlight zone.
4) all of the above.

Sheesh!
