they aren't. republicans had better margins in NC and Georgia than in Florida in the last six elections and biden is polling better there.Any reason why Georgia and North Carolina seem to be easier to win than Florida.
it just seems like that to us because democrats complain about florida more, but thats because its a more obvious swing state than NC (which Obama only won the first time with his smallest margin in the country) and Georgia (which democrats havent won in decades)
