Gallup’s says its daily Feb. 7-8 tracking report shows Hillary Clinton and Barack Obama are basically tied at 48 percent to 46 percent, within the survey’s 3 point margin of error. That’s down from her 5 point lead on Sunday and her 11 point lead in the Feb. 4-6 survey. If Obama gets a big bounce from tomorrow’s Potomac Primary – and polls show him in the lead in Maryland and Virginia – that could change the equation in the poll numbers.

John McCain is leading Mike Huckabee 56 percent to 25 percent.

A Gallup look inside the numbers of all the tracking polls between Feb. 1-9 adds that while Clinton enjoys a big gender gap over Obama among white women, the same is not true among black women. Black women favor Obama 66 percent to 23 percent, about the same as his 69 percent to 25 percent margin among black men. Clinton’s margin among white women voters is 59 percent to 31 percent. Gallup says Obama’s large lead over Clinton among black voters is less due to a rejection of Clinton than enthusiasm for Obama. Both enjoy nearly equally favorable ratings among black voters, and the same is generally true among white voters.

Clinton’s margin over Obama among Hispanic voters is 60 percent to 34 percent, with big margins among both men and women.
