5 of the first 10 presidents were re-elected for a second term.
George Clinton for his first term; Eldridge Gerry for his second. Both of them died in office.
As of 2014, there has been 43 presidents in the US. Currently, the president is Barack Obama and he is serving his second term.
Absolutely.
I am not quite sure what " went for" means to you. Only two presidents announced early in their administration that they would not seek a second term and they were James Polk and Rutherford Hayes.
No
As a group one-term presidents are not so successful which is why they were one-term presidents. Polk refused to run for a second term and he was probably the most successful one-termer. Taft would very probably have won a second term if Theodore Roosevelt had supported him instead of breaking with with his party and running as an independent against him.
27 of the 44 US presidents served more than one term in office. 19 of these were elected to more than one term in office. The other 8 served out the term of a president who died in office and were re-elected for a second full term. Only one president served more than two terms, Franklin D Roosevelt, who served three full terms and was elected for a fourth but died in office before finishing that term.
American presidents who are re-elected are required to repeat the oath of office.
I believe it's around 9 presidents.
