Sara Palin and the Same Failed Conservative Values

[[palin-p1]]

Like at past Republican National Conventions, there has been a lot of talk about conservative values. Nothing new there, but this time the convention has the feeling of a sinking ship.  The conservatives are doing a lot of  talking about the exact same Failed Conservative Values that they have been talking about for the past 30 years. It's the same Failed Conservative Values of indifference, incompetence, compassionate conservativism and corruption that brought us the disaster of Katrina. It's the same Failed Conservative Values of authoritarianism, secrecy, deception and violence that brought us the failed invasion and occupation of  Iraq. It's the same Failed Conservative Values of selfishness, greed and arrogance that brought us Abramoff and a conservative congress mired in a culture of corruption.   It's the same Conservative Family Values and Traditional Conservative Values of 'you are on your own', that have lifted the national misery index. It's the same fundamentalism, self-righteousness and hypocrisy that brought the sex scandals of Mark Foley, Ted Haggard, Larry Craig, etc. etc.

Should progressives confront conservatives at the values level and say that conservative values have failed?
