In his Talking Points Memo tonight, Bill O'Reilly said that the presidential race of 2016 will be the ugliest in American history.

O'Reilly pointed out that 50 percent of Americans disapprove of the job President Obama is doing, according to a new Quinnipiac poll.

"That has angered some of the president's most ardent supporters who are standing by their man, believing he is misunderstood," O'Reilly said. "But when asked what his accomplishments have been, there's really only one thing the left can point to: ObamaCare."

O'Reilly said that Obama's tenure has been "mediocre at best" and that the chaos overseas is clear to everybody except Obama, "who continues to put forth that his foreign policy has gained respect for America around the world."

"The Factor" host noted that when President George W. Bush got into trouble over Iraq and the economy, many on the right continued to defend him, because they were angry about all the criticism. 

O'Reilly said that it's the same thing with Obama, and his supporters are furious that his administration is being perceived as a failure. 

He also noted that Hillary Clinton's support among Democrats and independents has dropped by nine points since April. 

"Committed liberals are so angry right now, so furious that things are not going their way and that their standard bearers are losing respect," he said. "They are going to attack in unprecedented ways."

O'Reilly concluded that the presidential race of 2016 will be the "ugliest in American history."
