It'll continue to drop as she appears more in front of cameras. That shrill voice and irritating cackle, along with her arrogance and condescending attitude, not to mention her lack of accomplishments (ever) will sink her. The only thing she has ever done is be near by while somebody else was governing. She's never done shit herself.
Again, who on the Right can beat her. Her closest threat is Chris Christie and not all that many Republicans even trust him. You've got nothin.
If she runs, she will take the presidency.
