The Democrat Party has been getting away with election fraud since 1982
They are livid that the consent decree imposed on the Republican Party was lifted in 2017. This is an interesting bit of history and it helps to explain how the U.S. voting system got so messed up. Essentially, the Republicans sold the nation down the river. Even though they are no longer bound by the egregious consent decree, they still don't have the guts to fight for what is right.
