You just convicted her, if she is using PAC money.
The money in SarahPAC wasn't left over from the previous election, it's money that has been donated SINCE then. It's not subject, as far as I know to FEC rules regarding money spent on elections. Hillary used her PAC money for years after her election, and I haven't heard of anyone going after her for it.
Of course, that doesn't mean they won't TRY to beat Sarah up over it.
