So, was FDR a fine man or not?  
Nixon appealed to the 'silent majority' which you claim are all racist. 
In the  election of 1968 George Wallace took most of the southern states and Hubert Humphrey took Texas. Nixon took his home state of California, Florida and the mid-west and won the election.  George Wallace  had been a solid Democrat  until 1967. A strong segregationist and even stronger Democrat. Maybe your kind of Governor?  Or maybe Thomas Eagleton was,  whose bouts of depression 'unhinged'  the McGovern campaign so badly in 1972, he dropped out as the VP nominee.  Racism is a mental disorder too, but maybe he was just  depressed that segregation was ending...
.https://en.wikipedia.org/wiki/Civil_Rights_Act_of_1964....This brief history of the 1964 Civil Rights Act shows all those great Democrats that opposed it and how VP Humphrey had to attract Republicans to get it thru. Republicans voted by a margin of 80% to pass it, while Democrats almost killed it.
