As for whether to try the case or cut a deal-- that's a client's call but the client needs a lawyer with both oars in the water and an understandiing of and ability to explain the potential differential between sentences with the competing option.

  It's hard to say what her exposure might be without knowing the amount of relevant conduct ($) the prosecution can attribute. If the amount is amore than a million but less than 2.5 she will probably have an AOL in the low to mid 20s. It sounds as if her criminal histoty category will be at least  II.

   Just as an example 22 and II provides a sentencing range of 46-57 months; 26 an II provides for 70-87 months.

   The benefits of a plea and acceptance of responsibility  include a 3 level decrease in the offense level-- and often a more informal understanding theat the Feds won't attempt to pile on the relevant conduct and often go a little easier on forfeiture.

  This is purely a speculative estimate but, even with a plea,  I doubt she'd end up beelow a  total offense level of 19 which with a CH II gives a sentencing range of 33-41 months. If she goes to trial it could end up much higher. She won't get AOR; she might get obstruction of justice (+2) if she chooses to testify and the government might well try very hard to increase the amount of illrgal money attributed and push for other guidelines enhancements. Still, I doubt she would possibly end up with a sentrencing range where the top end reaches 10 years unless there is considerable money or actions not reported in these stories. Most likely the potential difference in sentence between a plea and a guilty verdict is 3-5 years at most.
