Webb is an old fashioned Democrat. Back in Roosevelt's day he would have been called 'an Al Smith Democrat' for opposing Roosevelt. Meany, the head labor leader in WW II era was another who was a strong anti-communist. The Democrats lost their way when they became left-wingers. A Webb resurgence would be most welcome in the Democrat party, even the Republican.
Webb is or tries to be a Hubert Humphrey Democrat rather than a Barack Obama Democrat. What he doesn't realize is that the constituency that gave Humphrey the Democratic nomination is gone and it isn't coming back.
The Democratic Party is now the radical party, not the liberal party. Obama and Hillary got where they are thanks to radicalized "minorities" and college kids/yuppies who vote on trendy causes like homosexual marriage, radical feminism, and gun control. The socially conservative or moderate working and lower-middle class whites who were once the core constituency of Truman, Humphrey, O'Neill, etc. are A. much fewer in number, thanks to mass Third World immigration and on account of economic policies that turned working/middle class into an underclass and B. voting Republican.
