Because that exact thing has happened literally hundreds of times, right? Why do I suspect you're one of those people that blames Obama for the response to hurricane Katrina?
As long as the GOP continues to view the solution to it's problems as needing to move further toward the extreme right, their slide toward irrelevancy will be irreversible.
Because we blame the Obama administration for its myriad bad policies, corruption and general fuckery, for which mischaracterizing us in whatever way you can is your only available defense.
Back to the OP, there is nothing wrong with GOP. I hope and pray the keep the recent SOP for elections to come.
