If you know anything about LBJ, you know he makes Obama look like a saint. He quadroupled down on Roosevelt and Wilson's big government socialist programs with his 'Great Society' and 'War on Poverty'. In selling those two programs (along with the mostly righteous Civil Rights Act) to a couple of racist governors on Air Force One, he said, "I'll have those ni**ers voting Democratic for the next 200 years". Fifty years and counting. And all of that was conveniently enabled by his becoming President instead of being left off the '64 ticket and/or sent to prison for what was being found in Congressional investigations against him. His legacy is the moral/legal double standard for establishment figures inside the Beltway--especially the President.
This is all just a drop in the bucket. And before you say conspiracy theory, so was Watergate originally. Establishment Republicans hadn't sold out yet.
I lived through the LBJ time period and was watching politics almost as much then as now. Your position on LBJ is very slanted.
LBJ was warned that by passing the 1960's Civil rights Acts that this would drive most "Southern Democrats" into the Republican Party, which it did, and yet he took that action anyway. Yes, the Democrats would gain some black votes, but do you actually believe that he thought this would offset the large number of whites in the South going Republican?
After Kennedy's tragic death, most of the country and the Democrats in particular wanted to continue what he had started, and Kennedy, very reluctantly I might add, more in the direction of more rights for blacks. The reality of the situation is that equal rights for blacks, women, and eventually gays, became more of a push by the Democratic Party but was fought against by most leaders in the Republican Party.
So, since LBJ "soiled socialism" as you claim he did, then I'm so glad to have lived through and helped contribute to that "soiling".
