Why do you think Trump let all those people out of prison early? That's right, he was trying to buy black votes.
Of course it would be a new voting base. You're a felon. You can't own a firearm. Places won't hire you for a job. But the Democrats come along, and promise if in power, they will make it legal for you to own a gun regardless of what you served time for. You mean to tell me you wouldn't vote for them? Or if they promise to create law that stops employers from discriminating against you because of your criminal record, you would vote Republican instead?
If you let felons vote, the Democrat party (and maybe even the Republicans) will start pandering to them. How would you like to be working at a shop where the guy next to you was in prison for murder, and he has a temper?
It's a terrible idea.
I don’t see Democrat’s advocating arming ex felons
What would happen if ex felons could vote? They would question why 2.5 million Americans are in prison, question the expansion of for profit prisons, question living conditions
They would not work to make rape and robbery legal
They may work to make the prison sentences less severe.
Of course you don't see Democrats wanting to remove the prohibition of firearms for felons, because they don't vote yet. But if we had a federal law that allowed them to vote, that might change.
According to research, by the end of this year, we will have 23 million ex-cons in our society outside of prison. That's a hell of a voting block that Democrats could take advantage of. And also in the estimate, there are over 600,000 more released every year.

One of the reasons our crime is so bad in this country is because our prisons are not enough of a deterrent. By lessening the deterrent we have, or removing it altogether, that makes it more dangerous for the rest of us.
