President Gerald Ford trying to run as a centrist in 1976 even though he had a pretty conservative record in Congress as a Representative from Grand Rapids, Michigan and as House Minority Leader. And then had a pretty conservative record as President especially when it came to fiscal policy and taxes. But also as it related to foreign policy and national security. But Ronald Reagan saw President Ford as not tough enough when it came to Russia and foreign policy in general and was a basis for running against him in 1976.

I don't have the exact date on this, but I believe this is early 1975. The year I'm sure of and it was just after Ronald Reagan left the California Governor's Mansion as a two-term Governor of California. 1975 representing a new Congress with the next major national election being the 1976 presidential election. With the speculation in Washington being who was going to run for president. President Gerald Ford who inherited the job from President Richard Nixon in 1974 when President Nixon resigned. And would Ron Reagan run against the President or not in the Republican presidential primaries.
