Considering JD Scholten, Tim Ryan and Joe Kennedy may all win Senate seats and are 2028 Dem Prez prospects in 2028, no the GOP have elders in McConnell, Graham whom may be defeated in 2020 and new generations of Dem Leaders emerge in the Senate in 2020s, so no.
I love this bog standard old Atlas analysis, "Democrats have these amazing candidates, Republican candidates are all terrible...."
Then half the time these amazing Dem candidates get caught in a scandal, or run and get destroyed or end up losing to a crappy GOP candidate simply because of demographics or the cycle.
If I had a dollar for every time: someone was sure that Rob Portman was going to be defeated because of his ties to Bush or Pat Toomey was going to be defeated b/c he is more conservative than Santorum, and don't get me started on Missouri.
There is this pre-disposition on this site, to proclaim every new, young moderate Democrat from a red state as the next JFK.
Aw man, this takes me back. Remember people hyping Ed Fitzgerald? Good times.
