But the poll also reveals a gender divide. 41 per cent of men would give their support to Obama. Compared to 51 per cent for Romney. 50 per cent of registered women voters would give their vote to Obama. Compared to 42 per cent for Romney. "It's pretty clear when we look at long term tracking numbers in the presidential race that it's been fairly stable and tight, expect among the different genders" Nanos says. On Tuesday at the Republican National Convention, Mitt Romney's wife Ann Romney reached out to women voters. But it's still unclear if the GOP will be successful. Nanos says the reality is that Republicans will not win the White House unless they do a better job appealing to women. Watch this week's Nanos number above.
