In a YouGov poll conducted between July 25-29, 59 percent of Republicans surveyed said they would prefer a president under the age of 75. Trump celebrated his 78th birthday in June. Forty percent said they had no preference, and just two percent said they would prefer a president over the age of 75.
Exactly. They are only saying this now because Biden dropped out.
And yes, I am guessing it was a rounding error. There’s always a margin of error on these things after all.
