I have now known several felons. I don’t think any of them would have taken the time to vote. They are too concerned with other issues; getting high, getting thrown out of their rental, getting their car repossessed, making bail for their wife/husband. The list goes on. They are not the type to register unless it is done automatically.
I am sure that some quantity of them go on to lead productive lives. I only know one in that category now and it’s because he has two teenagers. (He still has a serious impulse control issue, but he is more adult about it than he was when he saw an opportunity and “took” it.)
And the Dems with their hungry clipboards and registration cards know where they live.
Dems will vote for them.
