Yes, she would be a good president.
As long as she is consistent with what she has espoused to this point.
She claims fealty to the Constitution (albeit somewhat misguided). If that stays, she'll be good.
If she is effective, it will only be with regards to cutting down government.
My biggest concern is that she'll follow her father's willingness to go to war. I used to be a huge fan of Dick Cheney, but I was truly disappointed in the Bush administration which I felt he could have influenced more.
