Sorry if this has been asked before. What would happen if TFG drops out of the election?

6. The Constitution is silent on this matter

and the only situation that is close was when Horace Greeley passed away between Election Day and the meeting of the Electoral College. The EC delegates split their votes for Thomas A. Hendricks (42 votes), Benjamin G. Brown (18 votes), Charles J. Jenkins (2 votes), and David Davis (1 vote) and there were 3 that were cast for Greeley (Congress did not count those).

Since then there have been no laws or other guidance as to what to do in the case of a candidate dropping out. So after the next sentence, this is all speculation.

Individuals don't vote for a person, they vote for a slate of Electoral College delegates who then vote for whomever they are pledged.

I would posit that if the candidate to whom they are pledged is no longer in the race, the Electors would be freed to cast their vote for whomever they wish (which would probably be the person that state's party selected as a secondary option).
