Some experience better prepares you that other experience. Being a governor or a senator for at least a few terms is better experience than being a community activist who just walked in the door of the US Senate before running for President. Hillary has experience, but by the time she would take office she'll be 70. America doesn't need any blue haired elderly ladies having their finger on the button. Joe Biden is a good example of what can happen to your mind in your 70's.
