There was no need to change George Bush. I think Bush would have allowed the giant bankrupt companies to fail and he would have withdrawn the $700 billion bailouts given to bankrupt companies. Today world high inflation would have been invisible. I think $ 9 Trillion Obama bailouts is causing present world high inflation. Inflation in other countries are seriously high and unbearable and unstoppable. Thanks to Barack Obama.
God is alone and lonely so God created Obama to have some fun. Donald trump said "USA has become the laughing stock of the world". All of Obama's decisions result in negative for the USA economy and its citizens. Obama is the world's most powerful person.
