The Bush administration was a thoroughly corrupt one and essentially fascist in character, but with some characteristics historically associated with the "left" too, such as overspending and large government. Similar in some ways to the Reagan administration, which promised a balancing of the budget, and small gov't, but did neither. Incidentally, presidents who claim to be "strict constructionists" are playing games. Strict constructionists are those who favor close adherence to a literal reading of constitutional provisions. These presidents---Reagan, Nixon and Bush--favored certain agendas, such as a tough on crime approach, the "war on drugs," absolute opposition to abortion, and jingoism. They also favored a very liberal reading and application of the "Commerce Clause" and "Necessary and Proper Clause," spelling enhancement of federal power, and a lessening of state power and sovereignty (and personal liberty). Historically, "rightists" have supported individual freedom, free enterprise, and the right of privacy. Yet, recent Republican presidents have favored the violation of privacy, compromise of due process and the rise of corporate capitalism..which opposes competition (and genuine free enterprise).
The Progressive Movement is usually associated with such things as welfare programs, civil rights, peace, transparency of gov't, labor rights, improving the quality of life...including equal opportunity and education, and innovation. Yet this movement has been a lie to some extent, in recent years. After all, Truman and Johnson prevailed over the Korean War and Vietnam War, respectively, and certainly Johnson was no proponent of transparency in gov't. And, Truman was responsible for dropping two nuclear bombs--hardly the act of a pacifist. Come to think of it, Democrats Wilson and FDR were "in the house" during WWI and WWII, also.
Yet, Johnson was certainly a progressive relative to the social and civil rights programs which he pushed through.
Now back to recent history. Americans voted out the Bush people, as they had become disgusted with the lies and wars, and because Mr. Obama promised major changes. Nonetheless, Obama has honored none of his promises...or what might be called the Progressive Tradition. He has embraced essentially the very same agenda as Bush-Cheney (Strong prosecution of three overseas wars and a domestic "War on Terror," with concommitant continuation of erosion of constitutional protections)...with a liberal gloss..in the form of really nice rhetoric and a push for a meaningful health care program. As the last turned out to be a sell-out to the insurance industry and pharmaceutical industry, and that he ALSO bailed out Wall Street (but not the average citizen), this man is hardly a progressive in any meaningful sense. What's more, "Liberals" in Congress showed their true colors by refusing to impeach the Bush principals, and to challenge the illegal and lunatic wars which kept on, unabated (and the infernal "War on Terror" and "Patriot Act").
This is the mess we now have, with few true liberals or conservatives. And, this is exacerbated by some extreme rightists (lately called Neocons or Teabaggers), with many favoring the wars and Patriot Act, yet with many insisting on personal freedom and right to privacy and due process (and real free enterprise), too. My guess is that today's "Liberals" are so fearful of these people, who are extreme in SOME ways, that they are shaking in their boots about making any real changes, such as ending the wars. More important is the fact that those in power do not really WANT to end what the "powers that be" have ordained, which is obviously endless war, plenty of governmental spending, restriction of personal rights and the enslavement of everyone in America, save the Elite. And, the realization of what used to be called "statism," and what has come to be known as the "New World Order."
