she's the vice president. one of her few real jobs is to certify the election. if she doesn't then the electoral college is thrown out and the house decides who becomes the next president by a vote. this is what pence should have done because of all the chicanery in democrat strongholds swinging entire states in 2020. note that the house does not have to choose any of the candidates that ran for us president. they can vote anyone they want to be the next president and they can vote over and over again for different people until one actually gets 51%. if pence had done his job, then the house probably would not have voted trump for president, but they definitely would not have voted biden either.
