I think her problem is that she doesn't like giving yes/no answers, because she knows things are more complicated than yes/no, so you get situations like the debates and interviews where the moderators/interviewer literally demands a yes/no response and she starts going into nuance and detail and in effect says "I can't give you a yes/no answer" and they keep pressing her and she finally gets exasperated and gives a yes/no answer, but to viewers watching who want simple answers to complex problems, they view this as "dancing around the question".
You can see this all the time in comment sections of interviews when these questions are asked, with many politicians from any party: "Why can't they just answer the question!?!?!" = "This person isn't giving us a response that's easy to understand. They must have something to hide".

But to answer the yes/no question:
She's no more dishonest than your average politician. Voted yes
