Isn't the meaning obvious? Blacks were often attacked when they went to the polls. The statement isn't actually that racist. It's more of an observation.

No, you uncle is not right. I means the person gets nervous or some other condition when it comes to election. And he sweats like a (N) as they are known to sweat easily.
Reply:It certainly means your uncle is racist. Other than that, the expression makes no sense.
Reply:It's an extremely racist remark....it refers to when blacks were slaves and sweated during long exhausting field work and were not allowed to vote to improve their situation....were not even allowed to speak up about it....I'm not sure why election day is relevant but it probably has a historical meaning pertaining to an activity involving slaves on that day...no one should make a statement like that...please don't adopt it into your vocabulary...
