No law prevents from being elected president again

University of California, Los Angeles law professor Richard L Hasen – one of the country's leading experts on election law – has consistently said that nothing in the US Constitution bars a convicted criminal from running for the nation's highest office. “Legally, nothing changes with Trump's status as a candidate,” Hasen wrote in his Election Law Blog on Thursday.

“The Constitution contains only limited qualifications for running for office (being at least 35 years old, a natural born citizen, and at least 14 years a resident of the US),” Hasen wrote.
