There are no Maginot Lines in politics, no permanent positions. Politics is swordfighting, a swirling dance of thrust and parry. Before JFK, the Democratic Party was the home of Southern racists. Republicans started as the party of Lincoln. More recently, liberals used to be FDR New Dealers, before they became Clintonite corporate neoliberals. My point is that, in the current world, political labels are meaningless (if not downright misleading), policy papers and talking points are meaningless. It is by their actions that you know politicians.
