The party that touts personal responsibility hasn't taken any responsibility for their 8 terrible Republican years, their destruction of the economy, their pointless, false war in Iraq, their Patriot Act in violation of the Constitution, their hypocritical, adulterous politicians, and a slew of other bad behaviors. I don't think they ever understood the phrase.
You are right, they need to start offering up some solutions. Haven't seen anything useful from them for years.
