Sen. Tim Kaine says he'll run for a third term

Virginia's Sen. Tim Kaine announced Friday that he'll run for a third term, after mulling what it would mean to serve another six-year term on top of a political career that will have spanned 30 years by 2024. 

"When I ran for the Senate in 2012 — it's at least an eight-year decision," he said, the sum of two years of a campaign and a six-year term. "Grappling with an eight-year decision at age 64 is different than at age 53 or 42."

Nonetheless, Kaine is younger than many of his Senate colleagues — and 16 years younger than President Biden, who is likely to announce his own reelection bid soon after the State of the Union address next month and at 80, is the oldest man in history to hold the office.
