In 2006, Republican House candidates edged Democrats among that group by 51% to 47%. Now the Wall Street Journal-NBC News poll shows Americans earning more than $100,000 want Democrats to win the White House next year by 48% to 41%, and want Democrats to win control of Congress by 45% to 42%.
Campaign-finance data represents another yardstick. The top five Democratic presidential candidates raised $242 million through the first three quarters of 2007, according to Federal Election Commission figures compiled by the Center for Responsive Politics. The top five Republican candidates have raised $167 million".
