Pew Poll: Obama knocking off McCain's socks

A new Pew Poll of likely voters finds Barack Obama enjoys a significant advantage over John McCain:

Obama 52
McCain 38

The poll was conducted over landlines and cell phone between October 16 and October 19. The poll had a huge sample: 2,382 likely voters with a margin of error of +/- 2.5%. Pew notes:

A widespread loss of confidence in McCain appears to be the most significant factor in the race at this point. Many more voters express doubts about McCain’s judgment than about Obama’s: 41% see McCain as “having poor judgment."
