Of course Clinton will have a hard time handling the office of the presidency. She is still currently being investigated over her email scandal and recently it has been proven she sent top secret emails to her private server. She can not defend her self in many areas and the Wall Street question from the debate was just one of them. This is because she lies and is bad at covering it up. One she could get away with but not both.
In my opinion Hilary Clinton has all bases covered when it comes to being qualified to potentially be our first female president. It is understandable to me that any of the candidates will occasionally stumble on a question. That is not at all hard for me to understand with the whole country watching them.
Secretary Clinton has a proven history of taking corporate donations and speaking fees, indicating that her presidency would be heavily influenced by those entities. No billionare company pays for anything without expecting something in return. She might be a decisive president, but that doesn't mean she would make the decisions that would benefit the ordinary people of the US.
In case anyone didn't pay attention all those years ago, Hillary Clinton does not want to be president.She said that the president has no real power and that seems to be what she wants. I believe she is only running so that her agenda can be put forth. She will tie Bernie Sanders all the way until he beats her by a slim margin and then she will refuse to capitulate until he promises to further her agenda. You know, like she did with the Affordable Healthcare Act and making Obama take the responsibility.
