I think the single biggest mistake the Democratic Party made was when it 'abandoned' a Trumanite foreign policy.
While the collapse of the 'Evil Empire' was very much realised by Reagan and accomplished under Bush (41), didn't it represent the ultimate triumph of the Truman Doctrine?
It would seem that the US electorate in the main have favoured a 'hawkish' foreign policy, which partially explains a preference for a Republican President.

I think you are 85% correct. There are other issues where the Dems have gone wrong in the eyes of a lot of Americans, but abandoning the Truman/Kennedy foriegn policy platform the biggest one for most people.
