Donald Trump (All General Trump Conversations Here) Obviously if he thinks he won, he wants to find the missing votes, like you would if you lost some dollars you would want to find the missing money. Different from asking to forge money or manufacture votes. — FreeEmotion
If you're trying to contextualize this so that we can better understand the meaning of the word "find," you have to consider the whole context, not just what Trump's personal belief was about the validity of the election (and who knows what that really is). The role of the Secretary of State is to count the votes and to declare a winner, regardless of who that might be. Obviously there are times when the party of the Secretary of State will not be the party of the person who wins a given election, but that doesn't change the charge of the SoS. That is to say, the role of the SoS isn't to go out and "find" votes for a particular candidate like he's on an Easter egg hunt. What he is to do is count the votes and be sure the election was valid, which he did. In this case, the SoS counted the votes 3 times, once on election night, then he conducted a hand count, and then he did an electronic recount, and then he certified the election.
And to further contextualize this, Trump knew very well when he spoke to Raffensperger that Raffensperger did not believe the election to be stolen, so Trump knew very well that Raffensperger would not have accepted such a strained definition of "find" when Trump asked him to find more votes. That is to say, even if Trump truly believed votes were stolen and then stuffed into some nook and cranny, he had no reason to believe that Raffensperger would take the term "find" to be anything other than a euphemism for the term "fabricate." It makes sense that one would use a term how they expect the listener to understand it, unless Trump only meant to be talking to himself.
And to further contextualize this, within the same conversation, Trump told Raffensperger how mad Georgians were about this result and there was the allusion to criminal prosecution for some unknown sort of crime if additional votes weren't found. What this means is that we have the most powerful man in the world (although his power is fading fast) telling a local SoS to locate ballots that will swing the state's election in his favor, and if the votes aren't found, Raffensperger will lose his next election and will then be off to jail.
That's what happened. You can fully support Trump if you want to, but trying to cast the conversation between Trump and Raffensperger as an innocuous call to the lost and found department in search of the votes Trump thinks might have been left at the booth at the diner is pretty much nonsense.
