I would expect that to require an extremely huge amount of money and be impractical.

Candidates + parties + PACs + lobbying + think tanks + advocacy organizations spent $10B in 2018 in the US, whereas the US almond industry made $12B in 2018. So I expect political spending to not be able to change ad prices very much compared to commercial ad spending.
