Sorry ... I would have considered a Democrat like Hubert Humphrey to be moderate ... but he lost in 1968 and now we will never know. All the Democrats since then (and at that time if we include LBJ) were worthless. I am sorry I ever voted for the party of Jefferson Davis. Pointing out that all Republicans, since Nixon, have been worthless (and at that time if we include Nixon) doesn't absolve the Democrat failure. I am also sorry I ever voted for the party of Warren Harding.
We shall see, in the not distant future, how the US is a dead end of history ... because they are too stupid to survive.
