In fact, after World War II, the president of the United States is basically a lizard agent, 
whether it is the Democratic Party or the Republican Party, behind the control of the lizard people. 
The so-called two-party campaign isjust a facade used to deceive the world. Some of these surrogates tried to fight the Lizards behind the scenes, 
such as Nixon and Carter, and most tragically, Kennedy was directly assassinated by the Lizards. 
In recent American presidents, George H.W. Bush has half lizard blood, Clinton is a complete lizard man,
George W. Bush is a lizard man half-blood, Obama is a lizard man's agent,
 and Vice President Biden is a lizard man half-blood, who is specially responsible for monitoring Obama. 
 After Obama, the lizard man's original plan was to let the female lizard man Hillary take over as president, 
 but did not expect to kill Trump, and more and more Americans know the lizard man's plot and plan,
and finally Hillary failed to become president. In the past four years, the lizard people have been trying to develop Trump into a surrogate, 
but failed, so the lizard people are increasingly distrustful of human surrogates, such as Romney, Sanders, and aoc have been unable to gain the complete trust of the lizard people.
 Now the only lizard man who can pretend to be human and run for president of the United States is Joe Biden, whose real age is more than 300 years old.
