A Rasmussen poll released this morning shows Republican presidential candidate John McCain in a statistical dead heat with both Barack Obama and Hillary Clinton in New Jersey.

McCain holds slight leads against both Obama and Clinton in the Garden State, though both within the poll’s margin of error.

McCain leads Clinton 45%-42%, while he leads Obama by a slightly narrower margin – 46%-45%.

That’s a major change from a month ago, when Rasmussen showed Clinton beating McCain in New Jersey by 11 points. But while Clinton’s support seems to have plunged, Obama remains almost exactly the same – last month, McCain led him 45-43%.

The poll also measured President Bush’s approval rating in New Jersey. 28% of residents said he was doing “good or excellent” job as president, while 54% rated his performance as poor.

The poll surveyed 500 New Jersey likely voters, with a margin of error of plus or minus four percent. It was conducted on Thursday, March 27.
