Republicans just took a vocal public oath of loyalty to their President in which they promised to cheat in the the election. That happened. It's on video.
My claim is that you should vote for the other party. That sounds reasonable to me.
I voted in the primary against the incumbent. The incumbent won. I will vote for them because the Republican opponent is a documented sexual predator. That is literally true.
These are the "two sides" we are dealing with.
Note that this promise is itself illegal. It is a violation of 18 USC 597.

He literally says he'll cut a check for $5,000 for every adult american if the Republicans win both the House and Senate in the midterms.
You don't have to take my word for it: https://www.youtube.com/watch?v=q4NphZBfmnE
He's also stated that he can issue the money without help from Congress, which directly contradicts the idea that it's harmless bloviating about voting in a 120th Congress to implement specific policy:

... though that distinction shouldn't really matter.
The payout is very much a quid pro quo bribe for voters. No additional interpretation of his words is necessary: he's said it very directly himself.
Which is exactly why it doesn't apply. The money would go to even the people who didn't vote for him.
The law you're referring to is about paying people for votes. Someone giving their own money to voters who can prove they cast a ballot in a particular way.
Saying that you're going to have taxpayer-funded transfer payments is ordinary politics. If your interpretation was right then proposing to increase social assistance programs would be vote buying in violation of that law.
