The new Pew poll on likely voters portends a landslide of unprecedented proportions. McCain appears to have destroyed himself in this campaign:

Obama’s gains notwithstanding, 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,” while just 29% say that this trait describes Obama. Fewer voters also view McCain as inspiring than did so in mid-September (37% now, 43% then).

Palin has turned into a poison pill:

Currently, 49% of voters express an unfavorable opinion of Palin, while 44% have a favorable view. In mid-September, favorable opinions of Palin outnumbered negative ones by 54% to 32%. Women, especially women under age 50, have become increasingly critical of Palin: 60% now express an unfavorable view of Palin, up from 36% in mid-September. Notably, opinions of Palin have a greater impact on voting intentions than do opinions of Joe Biden, Obama’s running mate...

A steadily growing number of voters say that McCain has been too personally critical of Obama: 56% say that now, up from 42% in mid-September. By contrast, just 26% say that Obama has been too personally critical of McCain, which is largely unchanged from mid-September (28%).
