A 50-50 Senate is more politics nerd parlor game than realistic outcome this fall. After all, it’s only happened twice. But were the Senate to be divided straight down the middle, it would make Biden the ultimate tie-breaker — a dream come true for a guy who spent 36 years in the institution and a potential opportunity for a VP who hasn’t ruled out running for president.

“He’d like two years of being the deciding vote, back in the cloakroom, in the Senate gym,” said former Sen. Ted Kaufman (D-Del.), Biden’s longtime chief of staff and still a close friend. “I think he would revel in that.”…

Back in the Senate again, Biden could attempt to make himself the deal maker who could rally the Democratic base and, for a wider set of voters, be the man in the spotlight getting things done in Washington…

“When you look at the map, it’s totally feasible,” said a national Democratic strategist.
