(AP Photo/Chris Carlson) Barack Obama, who claimed a majority of pledged delegates last night after his win in the Oregon primary, has opened up an 8-point lead over John McCain in national polling, reports Reuters. Obama, who was tied with McCain in the Reuters/Zogby poll a month ago, also doubled, to 26 points, his lead over Hillary Clinton among Democrats. In a Clinton-McCain matchup, the two candidates are at level pegging. Obama outpolled McCain 48% to 39% on the key issue of economic competence, which McCain led by 3 points last month. The Illinois senator also leads among independents and some demographics that he has struggled with in the primary: Catholics, Jews, union households, and the working class. McCain led among whites, NASCAR fans, and voters over 65. Read These Next Death certificate reveals Brian Wilson's cause of death. UPS driver hits the Slip 'N Slide with some partying teens.
