The sentence that uses a subjective pronoun correctly is the first one - Laura and I have written an original play for this year's festival.
The second sentence is incorrect because the word him is not subjective, and neither is her in the third sentence, or them in the last one.
Beeeeccccaaaaauuuuusssseeee..............we allow Democrats and Republicans to run for politics.....idk that’s my best guess :)
