You really can't be yourself when stumping for someone else. We'll have to see what emerges after she's paid her debts and runs on her own platform...that is is she chooses to do so.
Sure you can. It's disappointing that she doesn't do this.
I don't consider this some unforgivable sin, just a disappointment after all the "rebel" stuff. As you say, once she's running herself, it'll be clearer who she really is. But I'm starting to suspect she won't be running for office again.
