Realignment is as much about voters switching parties, and for that, we have the data. By the 1952, and 1956 elections, far more southern whites were voting for Republican candidates. Reason was Ike (wanted to ignore civil rights), and Barry Goldwater believed that states' rights was sacrosanct. Richard Nixon promised to lock them up, and Reagan said "government is THE problem." All coded words that said to voters "hey, I'm a white supremacist like you, vote for me and blacks will suffer." That didn't always happen because these coded tactics were just meant to put people into office, plying their racial fears.
You can put me in any camp you want to--especially if that makes you feel better. The U.S. Constitution creates and sustains the federal government. Read it. There was no federal government before its creation.

Oh, what's the use? you don't read anything but forums and Glenn Beck or Rush or Fox. There's nothing I can say to point out the errors of your reasoning. Your mind is made up. You play gotcha history and that's your prerogative.
