In a potential Obama-Romney election, 46 percent of
voters would back Obama and 45 percent Romney if the election were held today. The president’s narrow advantage is well within the poll’s three percentage-point margin of sampling error.
And behind those numbers is a striking contrast: 74 percent of Obama backers say they are voting “for” him rather than “against Romney” (21 percent). Yet for Romney, his support is mainly anti-Obama. Fifty-eight percent of Romney voters say they would be voting “against Obama” rather than “for Romney” (33 percent). FOX News
