Humphrey was more dovish than Nixon. After the 1968 election he openly turned against the war in Vietnam. The black ghetto riots won that election for Nixon. The electorate rewarded Nixon for ending the black ghetto riots by giving him a landslide victory in 1972. The continuing increase in black social pathology won the presidency for Reagan.Why do you keep repeating shit that was debunked? The Democrats didn't run a dove in 1968. They ran Humphrey, who was so afraid of Johnson, he didn't take a firm position on the war until the end. In fact, his full throated condemnation of Wallace's racism and the Vietnam War brought him pretty close to winning.
The black ghetto riots and increases in black social pathology destroyed the New Deal Coalition. Race wrecked liberalism.
