@BillRM,
I agree with BillRM on this subject (not that my opinion counts for anything).
I heard the phony states rights arguments to defend Jim Crow as I was growing up. Still makes me sick. Those same people were heavily recruited to join the Republican Party by the GOP leadership, beginning with Barry Goldwater and jerks like Phyllis Schafly and Pat Buchanon.
When I was in my early preteens, my white Texan parents (who were supporting Eisenhower for President) attended a Republican precinct convention during one of those Presidential election years. They were the only whites there. Most of those black Texans were eventually driven out of the Republican Party by conservatives who sided with white Southern conservative so-called "Democrat" segregationists to defend racial discrimination against black Americans.
The conservative John G. Tower was the first Texas Republican to be elected to the U.S. Senate since Reconstruction in a special election runoff in 1961 that pitted him against conservative Democrat William Blakely, who was a dyed-in-the-wool segregationist. Tower's voting record on civil rights and other race-related bills turned out to be EXACTLY IDENTICAL to that of the Southern conservative segregationist Democrats. In other words, he voted exactly the way Blakely would have voted! (Incidentally, Tower owed his victory in the runoff election to liberal Democratic voters who were opposed to Blakely.)
My wife, who voted for Mitt Romney last week, was a Republican until just a few months ago. She's now an independent because after all these years she finally got sick and tired of all the white racist bigots who found a home in her party. She got tired of the likes of Strom Thurmond, Jesse Helms, Trent Lott, and Haley Barbour.
