A lot of things have reversed. It used to be the Democrats were also against free trade, while the Republicans were all for it. Now, the Democrats are fanatical true believers in free trade, even more so than the Republicans.
There was once a time when Democrats would advocate for peace, and they would question/criticize the government, especially the Defense Department, Hoover's FBI, the CIA, the Nixon Administration. They used to be more cynical about government and corporations, and they would advise everyone to "question authority." Now, they've become very naive and unquestioning about government, while simultaneously lambasting Republicans as "conspiracy theorists" and "anti-government nuts." Moreover, the same people who used to march in protest against the government over its military aggression have themselves turned into warmongers and militarists.
