I will say right up front that this is not specifically a Republican flaw, but is the way virtually all humans behave.
Anyway, I think it is fun to compare the things that our current administration is responsible for and those they are not - according to them, of course:
Responsible for: GDP growth - due to wise tax cuts!
Not responsible for: job losses and mcJobs - just the economy, we cant control everything!
Responsible: doing everything possible to win the hearts and minds of Iraqis
Not: torture of prisoners in Cuba, Iraq, or Afghanistan - those are isolated cases, isolated to three separate continents.
Resp: tax relief
Not: Ballooning deficit - it's ok to take a revenue cut (taxes) without an expense cut (spending)
Resp: Invading and liberating Iraq
Not: Everything after
Resp: good stuff - so re-elect us!
Not: bad stuff - so re-elect us so we can fix it!
