Polls show that Barack Obama is poised to receive a larger share of white voters than any Democratic candidate for the past three decades, Politico reports.

“No Democrat has won a majority of white voters since Lyndon Johnson in 1964. John McCain has shuffled between 48 percent and 50 percent support in recent weeks — which would be the lowest share for a Republican candidate in a two-man race since Barry Goldwater’s run.

“If Obama’s share holds, it would top the 43 percent of white voters who backed Bill Clinton in 1996, when the Democrat won a plurality among white females and 38 percent of white men, the best performance by a Democrat in all those categories since 1976.”
