Unfortunately, she was on the wrong side of that imo. For 5 years she was a U.S. Treasury Dept Attorney, representing the IRS (in her words)"in hundreds of cases" (both civil and criminal) prosecuting people who underpaid or failed to pay their taxes.
Other than that, I like just about everything about her and hope she does throw her hat in the ring. She'd be on my short list.
Well...at least she KNOWS the IRS! And, maybe could find a way to disempower them!
