I agree, it’s best to not pull at the fraying threads of democracy, but it’s not like there’s never been a controversial election before. Take the 2000 Gore v. Bush election, for example.
If Reuters wants to expose the laying of groundwork, then they have to do more than baiting a fairly mundane statement out of a single R. They have to collect evidence of republicans doing it themselves. This is just lazy reporting that plays to peoples fears.
