McCain Support Continues Downward Spiral

Obama Leads by 19 Among Those Who Have Already Voted

Pew Research Center

Overview

Barack Obama leads John McCain by a 52% to 36% margin in Pew’s latest nationwide survey of 1,325 registered voters. This is the fourth consecutive survey that has found support for the Republican candidate edging down. In contrast, since early October weekly Pew surveys have shown about the same number of respondents saying they back Obama. When the sample is narrowed to those most likely to vote, Obama leads by 53% to 38%.

A breakdown of voting intentions by demographic groups shows that since mid- September, McCain’s support has declined significantly across most voting blocs. Currently, McCain holds a statistically significant advantage only among white evangelical Protestants (aside from Republicans). In addition, Obama runs nearly even with McCain in the so-called red states, all of which George W. Bush won in 2004.

Just as ominous for the Republican candidate, Obama holds a 53% to 34% lead among the sizable minority of voters (15%) who say they have already voted. Among those who plan to vote early but have not yet voted (16% of voters), 56% support Obama, while 37% support McCain.

While Obama’s support levels have not increased much in recent weeks, a growing percentage of his backers now say they support him strongly. Currently, 74% of Obama voters say they support him strongly, up from 65% in mid-September. A much smaller majority of McCain backers (56%) say they support him strongly, which is largely unchanged from mid-September.
