It is complicated because the rules are different in each state. Also, Trump was convicted in New York state but he resides and votes in Florida.
For out-of-state convictions, Florida defers to the other state’s rules. New York would allow Trump to vote if he resided there because he is not currently in prison, so Trump can vote in Florida legally.

While W. sucked in many ways, there is no way he is the worst. Off the top of my head I can easily think of four better contenders: Franklin Pierce, James Buchanan (both guilty of pro-slavery fuckery before the Civil War), Andrew Johnson (fought to let the Confederates off the hook after the war and opposed the 14th amendment), and Donald Trump (first president to be impeached twice, first to be convicted of a felony, and may be remembered by future historians as the spark that ignites the next Civil War).
Andrew Jackson was also a bastard, especially for his treatment of natives. But I meant Johnson.
