Florida Gov. Rick Scott hasn’t yet announced whether he plans to run for the U.S. Senate this year — but if he does take the plunge, it could put a damper on one of his last big goals as governor.

Here’s the problem: If Scott, a Republican, is elected to replace Democratic U.S. Sen. Bill Nelson, he could be forced to step down nearly a week before his term is scheduled to end. That’s because Congress — at least for now — is scheduled to start its 2019 term on Jan. 3 — before a new governor is sworn into office on Jan. 8.
