Second term curse

Is there such thing as a second term curse on a President? Ask those who served a second term and they may say yes. We look back in history and find President Lincon was assasinated in his second term. Then there is Bill Clinton and his intern fetish. Then there is George W Bush. Bushes approval rating was lowest in his second term. His first term he was considered a patriotic hero. Now we have Obama in his second term. He was elected by majority yet cant seem to get anything done. Scandels have been the norm for his administration lately. So is there something to this second term curse people talk about? I would say YES! Presidents who get elected to a second term want to continue their legacy and try to change the world. or at least the US. Most the time a second term ends in dissaster and or second term distrations for them to realy get anything done. We are expieriencing it now with Obama. Lets hope he can see through the distractions of conspiricies and is able to get something done. After all, thats what we hire a President for. To get things done.
