It's very hard to guess at a sentence without knowing all of the variables that determine the sentencing guidelines - even then we are not lawyers so it's an educated guess. If this is his second charge in a year, the judge is not going to like hearing that - we predict some county jail time for sure. If there were injuries or damages, this could get ugly. 

Sadly, it probably does. Criminal history plays a big part whether prison time is included in a sentence and for how long.

Without seeing the indictment and the charges, we would be guessing. I did federal time in Miami with some guys who were there for this exact charge. One got 36 months and the other 60 months. Your husband's prior history doesn't help, especially at sentencing. 

Jailing a person for child support delinquency is likely classified as a Contempt of Court charge. The "sentence" is a few weeks to shake the non-payer into paying. The time is related to the amount that is owed, for how long they've been past due and if there are mitigating circumstances behind either not paying or unable to pay.  The judge will normally release the offender once the outstanding balance is paid. If that is not possible, then some payment arrangement must

Any time the feds get involved, the seriousness escalates. It is You vs. the United States and they will force a plea down your throat unless you are really innocent and have about a million dollars to buy the best lawyers to put your case on in open court. If you lose, they will triple the commitment penalty of the plea offer or more at sentencing. It's a tough system to go up against.

Idaho isn't any different than the other 49 states. If you are found guilty, of the charges as you describe them, which could range all the way to attempted murder - you are looking at a very lengthy sentence in state prison. Since we do not know your person of interest's criminal history so there is no way we can accurately assess what might actually happen. If he has prior violence in his history, he is going to have a

There are a lot of factors that make up the outcome of this type arrest. Most states have a mandatory minimum for intent to distribute, so the "no priors" is not going to carry much weight. What was the drug? How large was the quantity? Where they in a school zone? Was there a weapon involved at the time of arrest? Depending on the state where she was charged, the sentencing guidelines will vary - a typical statute reads:

How is it that he only has to do 35%...?

You would need to call the Clerk of the Court in the jurisdiction where he was charged and convicted. When calling, ask for the Judgment and Commitment Order. This would be the document that catalogued the fine and/or punishment that the judge signed into the record. They might not give you the information over the phone so you'd then have to order the printing and mailing of the document (for a nominal handling fee) to your home. 

Depending on where he is, he will likely do 85% of the 36 months or 30.6 months. First-time offenders do the same time as the rest of the inmates.
