The Democrats are in touch with their base, which happens to be isolationist, quasi-socialist, and great believers is identity politics and entitlements.
The some “old fashioned” Democrats who naively think that there’s is still the party of people such as Franklin Roosevelt, Harry Truman, John Kennedy and Lyndon Johnson. It is interesting to note that about half of the Republican candidates for President started off as Democrats, but the party then luched to the left leaving them behind.
