Biden says the question isn't about his age: 'It's about how old are our ideas'

• Joe Biden made a forceful case that he's not too old to be president.
• Polls continue to show that Americans think Biden is simply too old to remain as president.
• At 81, Biden is the oldest serving president in the nation's history.

President Joe Biden on Thursday used his State of the Union to take concerns about his age head on.

Biden waited until almost the end of his address, but the president made it clear that he would not ignore the question consuming his reelection. He used a mixture of self-effacing humor and the cold realism of what he sees as the stakes in this election to make his point.
