Will collapse of Hunter Biden plea deal help RFK Jr. in his longshot primary bid against President Biden?

Will the potential collapse of Hunter Biden's plea deal with federal prosecutors give Robert F. Kennedy any political boost in his long shot primary challenge against President Biden?

Hunter Biden was expected to plead guilty to two misdemeanor tax counts of willful failure to pay federal income tax, as part of plea deal with federal prosecutors to avoid jail time on a felony gun charge. The younger Bien owned a handgun in 2018 – during a period where he’s admitted he was regularly using cocaine. That violates federal law, which prohibits drug users from possessing firearms.

But after the judge in the case refused to accept the plea agreement – due to questions of the constitutionality of the deal – Hunter Biden pleaded "not guilty" as federal prosecutors confirmed the president's son is still under federal investigation.
