The poll shows that Obama has lost significant ground since Quinnipiac's last survey, in late June. Today, just 40 percent of Virginia voters approve of the job Obama is doing, down from 48 percent in June. Fifty-four percent of voters disapprove of his job performance, including 62 percent of independents. A majority of voters, 51 percent, think he does not deserve to be re-elected, while 41 percent believe he does. In late June, voters were split evenly on the question of Obama's re-election. The Quinnipiac poll was conducted Sept. 7-12, surveying 1,368 registered voters. The margin of error is +/- 2.7 percent. For the Republican primary question, 591 voters were surveyed, for a margin of error of +/- 4.0 percent. In 2008, Obama became the first Democrat to win Virginia since Lyndon Johnson in 1964.
