Or whether anyone would have challenged her anyway....
People complain about the lack of a competitive primary, but given when Biden ended up dropping out, structurally, does anybody really think Josh Shapiro, Gretchen Whitmer, etc. had big incentive to throw their hat into the ring versus waiting until 2028?
Reportedly the only serious candidate who even remotely considered it after Biden dropped out was JB Pritzker, and the fact that he fell into line within about a day or two was probably a sign of how successful a challenge would have been.
