i think it's very important. >> he's hopeful. you saw that, he was using the word. you saw that when he was talking about mccain. he and mccain shared the fact that both of them have gone through experiences in their life that are far beyond what anyone should have to endure. when you think of what the criticisms are of the current president, it's never in public service. and there is this element of self-enrichment that he gets criticized for. i think all the things joe biden has run for president before, and struggled before, the main issue for biden, and he talked about, is that he was seen as a gaffe maker. politics moves so fast now trump has set the bar so far in a direction, he would be able to survive. the news cycle burns so fast and hot and out. >> age is obviously also something that he would have to consider and voters would consider. >> trump is 71.
