this is very possibly an illegal practice - according to federal rules

the federal rules say no "unfair changes" will be made and warnings of changes will be PROFUSE

democrats here can make the change quietly and inform only democrats that voting day has changed.

alternately: they can improve a democrat owned business which makes mailings to voters (the contract is worth millions)

meanwhile why would they change voting day: ONLY FOR THE WRONG REASONS, that's obvious
