Cardinal Staford may no longer be in Denver, but his foundational work leading to that honor, was done in Denver. Cardinalates come with particular jobs, like Archbishop of New York, or Prefect for the Congregation of Bishops.
Only rarely do individuals get the red hat as an honor (as Avery Dulles did the last conclave) and most of those are retired and unable to vote in papal elections.
I would wager Patrick Flores in San Antonio would get the red hat before Chaput, as San Antonio has a larger percentage of Catholics.
Patrick Flores will never be a candidate for a red hat. He is despised, and even his supporters concede that he has some sort of organic brain disease. sockmonkey who lives in the Archdiocese of San Antonio has a good read on the situation, and I hope she'll post her findings and opinions about Patrick Flores.
