It used to be that a felony conviction came with the penalty of having your right to vote revoked, & in most states you also lost the right to buy and or own firearms. Many states have now given rights back to convicts, shows you what people in this country know about their politicians & what's going on. The democrats have been working on that for years, it gives them more votes. So yes in many states you can vote as a convicted felon
Can you vote in jail? Pre trial detainee, misdemeanor charges only, yes you can if you get an absentee ballot, or your state does a vote by mail program! Convicted Felon, nope never, they don't allow felons to vote but they can be elected to some offices!
in California the only time you are not eligible to vote is when you have: 1) a felony conviction and you are still in state prison or serving your sentence in county jail under Realignment; or 2) when you are on parole, on post-release community supervision, or on mandatory supervision. If you are on probation or if you have completed your parole, post-release community supervision, or mandatory supervision you CAN vote! https://www.aclunc.org/vote/ Different States have different laws: http://felonvoting.procon.org/view.resource.php?resourceID=286 12 states have the right under certain circumstances to permanently remove your vote 19 states return your right to vote once you have been released from incarceration, parole and probation 4 states only require you to complete your incarceration and parole 13 states and DC only require you to complete your incarceration Maine and Vermont allow you to absentee ballot vote from within prison Keep in mind these are Felony charges, only 10 states have regulations on misdemeanor charges affecting your voting ability
