Hillary Clinton: Joe Biden 'Could Be A Good President'

"He's testing the waters. He deserves to test the waters."

Democratic presidential candidate Hillary Clinton would welcome Vice President Joe Biden into the presidential race, saying that he "could be a good president."

"I like Joe Biden a lot, and I think he is a great vice president," she told ABC News on Tuesday. "I think he could be a good president. There’s no doubt about that."

But Clinton refused to speculate on the chances of a potential rivalry between her and the vice president.

"We shouldn’t get into the politics of this back and forth because I don’t think it’s fair to him," she said. "He's testing the waters. He deserves to test the waters... If he gets into this election, there’ll be lots of time to talk about what he wants to do.”

Biden has been weighing a run in recent months, consulting with close advisers and potential donors. However, he has repeatedly indicated that he is unsure if he has the emotional strength to pursue another presidential campaign, given the recent death of his son, Beau.

"The most relevant factor in my decision is whether my family and I have the emotional energy to run," he said at an event in Atlanta on Thursday.

Clinton said on Tuesday that she sympathized with Biden's dilemma.

"It's such an emotional decision," Clinton said. "At the end of the day, this is a grueling, difficult journey that anybody who decides to run for president subjects themselves to, and you have to be really ready and prepared."
