The presidency is the Executive branch of US government. The president is the Chief Executive Officer. How many would offer a person with Hillary's background the position of CEO of their company? Anyone? Would you trust her with your checkbook?
There is only one intelligent choice for the president. As far as passing legislation, that duty rests with Congress. If Congress would actually do its job we wouldn't have so many requirements for president. For example, the president cannot legally change immigration law by executive order. Obama tried it and got shut down. In fact, the current president lost more unanimous decisions before the SCOTUS than the previous two presidents combined. We have a system of checks and balances in this country that is designed to protect us from would-be tyrants. Part of that goes away if Hillary gets in and can tilt the Supreme Court to the radical left.
