While that used to be the case, today, those in the know apply for civil rights restoration after they have served their sentence, and rights are often restored, including voting and gun rights.
If the judge if particularly friendly, a good lawyer might even get their clients criminal conviction expunged, so it will not regularly appear when they have a background check, and do not have to indicate that they were convicted of a crime when applying for a job.
But this is not a major issue, as while the majority of rights restorations are for guns, the vast majority don’t care if they can vote, and aren’t likely to have their record cleaned because of the nature of their crime.
That’s good to know. Makes sense too. El-Rushbo being a billionaire and a conservative is not likely to be involved in any crime.
