By looking at voter registration and data broker information you can connect that information, sure. On an individual basis it’s easy. But it’s a different matter to collect that data on all convicted criminals in the country within a given time period. The larger the time period the harder that gets, especially considering that people with older offenses and no recurring offense can petition the court to have their records sealed, making an accurate count harder.
And, speaking as someone who’s been on the wrong side of law enforcement a few times in my youth, political affiliation or leanings would not be part of the record unless it was relevant (e.g. politically motivated crime). At least, if it wasn’t part of my arrest or court records, then it can’t be true in all localities.
