Is it sad to see the once great Republican Party driven to acts of desperation to appease the Far Right?

They are even blaming Obama for the recent Terrorist attempts instead of thanking him for catching the culprit. Even the Democrats on the far left did not blame Bush for 9/11 or the Anthrax or the Shoe Bomber attacks. The Republican party once a party of many is now the party of the 15-20% of Far Right...what some call "crazies". Are you sad for the party and does all the Obama hate make them look petty and foolish?
