AFP., Washington.-Democratic presidential candidate Joe Biden said on Saturday that he expects "personal attacks and lies" from Donald Trump in his first televised debate on Tuesday, but was confident to deal with it. he acknowledged in an interview with the MSNBC television network .

“My guess is that it will be just attacks. They will be most personal. That's the only thing he knows how to do, ”he said of the Republican president.

“He doesn't know how to debate the facts. He's not that smart, "Biden said. “He doesn't know much about foreign policy, he doesn't know much about domestic policy. He doesn't know much about the details. "

In short, Biden predicted that "it will be mostly personal attacks and lies."

Tuesday's debate in Cleveland, Ohio, will mark the first time the 77-year-old politician has faced the president he has vowed to dethrone. The two septuagenarians will meet in two other debates before the November 3 elections.

But some of his supporters fear that Biden, who is prone to making mistakes, may waver in these televised duels in the face of rhetorical blows from the much more aggressive Republican mogul.

Trump has never stopped scoffing at the lack of dynamism of his rival, whom he dubs "Sleepy Joe" and attacking his mental acuity. However, the Democrat says he is prepared.

"People know the president is a liar," Biden said.
