I keep seeing people freak out about all the people running for President who could be running for Senate instead.
Rubio declared in April 2015, was considered a top contender, won three primaries, got beat in FL, finished third in the delegate count, dropped out in March 2016 and defended his Senate seat with little problem.
I think we will see people dropping out before Iowa and the field narrow down significantly after SC. Plenty of time for Senate contenders to refocus their efforts.
What about Beto who's running for president when he should really be giving senator another try ?
Pete can run for senate in 2022 after he loses.
Kamala and Bennet can run again in 2022.
Booker is cleared to run for his senate seat and president at the same time in 2020 and it looks like he's the only one in a similar position to Rubio (correct me if I'm wrong).
Warren, Gillibrand, Klobuchar, aren't up till 2024.
Great point though.
