Both parties have done it after stinging losses. Learn your history.The Virginia scheme is not an attempt to "fix" any problems with the electoral college. It is an attempt by Republicans to steal offices they cannot win with votes. Democrats have not tried to discourage Republicans from voting, have not tried to reduce voting hours in Republican areas but not Democratic, and have not tried to make the votes of Republicans count less than those of Democrats.
This is not a bipartisan tyranny. It is Republican and Republican alone.
