Former Vice President Joe Biden said he considers himself "the most qualified person in the country" as president and will make a decision to move forward with a '2020 bid in the next two months.
His comments came during a leg of a tour of books at the University of Montana, where Biden also recognized that he had responsibilities, including being a "gaffe machine", but said none of them it would scare from running.
Biden, 76, would join what should be a crowded field of Democrats, including several senators, trying to overthrow President Trump.
"I will be as honest as possible," Biden said, according to CNN and local media reports. "I think I'm the most qualified person in the country to be president." The issues we face today as a country are the issues that have been in my wheelhouse, which I have worked throughout my life. "
These issues, he said, include "the difficult situation of the middle class and foreign policy".
"Even my critics will recognize, maybe I'm not right, but I know a lot," added Biden, a former Delaware senator.
Biden was interviewed by the author and television personality Bruce Feiler, who checked out some potential liabilities of another Biden campaign. Among these: his presidency of the judicial committee during the hearings of Anita Hill, his co-sponsorship of the 1994 bill that many Democrats have long since disowned and his reputation as a "gaffe machine".
"I'm a gaffe machine, but my God is a wonderful thing compared to a guy who can not tell the truth," Biden said referring to Trump. "I'm ready to challenge all those things.The question is what kind of nation are we becoming? What will we do, who are we?"
"Whether or not I run, anyone running, I'll break my neck to make sure it wins," he added. "We can not have another four years."
Biden said he would confer with his family in the next few weeks if he ran.
Trump said he would like a Biden challenge. During a CBS interview during the summer, the president said that running against Biden would be "a dream", claiming that Barack Obama "pulled him out of the trash" to make him his traveling companion in 2008 .
Biden tried in vain for the Democratic presidential nomination in 1988 and in 2008, both times they retired after the poor performances.
That was a test, Trump said, that Biden "alone could never do anything".
