A breakdown of voting intentions by demographic groups shows that since mid- September, McCain's support has declined significantly across most voting blocs.
In the final days of the race for president, seemingly nothing but the algebra of the electoral map appears to have staying power.
With less than two weeks to go before Election Day, voters remain riveted to the presidential campaign. But liberal Democrats are engaging in far more activism than other partisan and ideological groups.
Coverage of the presidential race has not so much cast Obama in a favorable light as it has portrayed McCain in a substantially negative one, according to a new study of the media.
Campaign coverage increasingly focused on tactics -- including McCain's invocation of an Ohio plumber to represent the working man - as well as fights in battleground states and the parade of polls.
Obama is inspiring more confidence on several key issues, including Iraq and terrorism, than he did before the debates, and his margin over McCain as the candidate best able to improve economic conditions has grown.
For the first time in a month, the election generated more coverage than the financial crisis and almost one-third of that coverage was connected to the increasingly harsh tone of the campaign.
