Federal election law specifically names housing and utilities as items that cannot be paid from campaign donations, so she clearly broke the law by paying for her housing and utilities from campaign donations. And the fact that she falsified the expense reports over those payments tells me she probably knew she was doing something wrong.
If she'd decided to set aside her regular career to run for office, paying herself a reasonable salary to make up for the time off work, then I'd be a lot more sympathetic. As it is, it looks like she's a financial train wreck, robbing from the campaign coffers to make ends meet. Running for senate year after year appears to be her only real source of income and the only way she can support her lifestyle. I'm not sympathetic to that.
Couple that with the allegations of fraud elsewhere in her life, and the personal accounts from several people deeply involved in her campaigns, and it adds up to something pretty nasty. Again, I haven't had time to thoroughly review some of these other issues, and I withhold judgment until then, but if they pan out...
