Realistically, no, I don't think it'll happen any time soon.
Why? People simply feel that women are too "emotional" or "weak" to do something as important as run a country. Even Canada's only had ONE female Prime Minister, and that was not recent. To be blunt, stereotypes are just too deeply integrated into our social fabric. Women are simply "not meant to do leadership roles" (but this is not to say I believe this - I'm all for a matriarchy.)
Personally, I think a woman would do a fine job, if she had the right personality for it, but that's how it is with any job, not just presidency. People fail to realize that women can be just as cruel, vindictive and aggressive as any man - maybe even more so. Compare female and male sports teams for instance. Women's teams are VICIOUS. And do you see a woman roll around on the ground and whine when she gets tackled or kicked or breaks a bone? No, but you see a lot of it in men's teams.
Anyway, that's my two cents.
