"Nothing is more disturbing than having 'serial child molester' and 'speaker of the House' in the same sentence," Judge Thomas Durkin rightfully said.
Hastert also received an order to pay $250,000 into a victims' fund as well as two years of supervised release after serving his sentence.
Hastert also acknowledged his attempts to mislead the FBI as it began the investigation into abuse claims against him.
This criminal deception led to a separate investigation of his victims for false accusations of sexual abuse.
The FBI ultimately discovered the truth during their investigation into the accusations of Hastert's victims, but the prosecution team will avoid using Hastert's obstruction of justice against him.
Perhaps the desperate pleas of Republican lawmakers swayed their judgement.
"We all have our flaws, but Dennis Hastert has very few. He is a good man that loves the lord. He gets his integrity and values from Him. He doesn't deserve what he is going through. I ask that you consider the man that is before you and give him leniency where you can," said Former House Majority Leader Tom DeLay in a letter to the judge.
Hastert's attorneys filed dozens of letters of support from lawmakers, bureaucrats and constituents to the court.
While the case revolved around a hush money investigation, the sentencing hearing primarily focused on the sexual abuse claims that arose during the case.
The allegations call into questions many aspects of Hastert's past and the GOP, which has produced many similar scandals of the years.
In 2006, a House Ethics Committee found Hastert to be "willfully ignorant" in responding to claims of Rep. Mark Foley sexually abusing 15-year-old House pages and former pages.
With their anxious defense of Hastert's pedophilia, some members of the GOP establishment appear to be as warped as their neoconservative ideology.
