WASHINGTON - President Obama and his Republican challenger in the November elections, Mitt Romney, are neck-in-neck in a new national survey released Tuesday. According to a Washington Post/ABC poll, Obama and Romney are tied at 47 percent a piece among registered voters - virtually unchanged from late May.

The survey also finds that 75 percent of Obama's supporters are voting for him, while 59 percent of Romney's supporters back him out of opposition to the president. "Romney’s numbers on this measure resemble [John] Kerry’s in 2004," a poll memo concludes, referring to the Democrat's 2004 nominee.Obama - who introduced a new proposal Monday to extend only the middle-class and lower-income portions of the George W. Bush era's tax cuts - is roughly on par with Romney on the issue of taxes.The survey finds  46 percent of Americans trust Obama to handle tax policy more, while 45 percent trust Romney. On health care, 46 percent trust Obama to handle health care, while 45 percent trust Romney. On the deficit, 70 percent trust Romney while only 25 percent trust Obama.Americans are just as divided on the issue of Obama's health care law, with 47 percent in favor, and 47 percent opposed in the aftermath of the Supreme Court case that upheld the law.The poll surveyed 1,003 voters, with a margin of error of plus or minus 4 percent.
