Why would she be a horrible president? She's a politician, and as far as I'm concerned, it's a genderless designation. Frankly, from looking at the list of candidates on both sides, IMHO, no one is more qualified than Hillary to take the seat.
She has handles a lot of her campaign issues, which will probably be her platforms, in the past and I do trust her with the issues that she knows best. Keeping in mind that it doesn't matter who will become president, I doubt that person would have a blank checkbook that our currrent president is wielding.
Maybe, just maybe in times like these our country can use a fresh change, be it a female president, a black president or a hispanic president.
