“Electoral”

I have always pronounce “electoral“ with the emphasis on the second syllable. This is the first pronunciation given by Merriam-Webster. The word is related to “election,” of course, and no one seems to place the emphasis in that word other than on the second syllable. Merriam-Webster gives a secondary pronunciation of “electoral” with emphasis on the third syllable, however. Frankly, this is a pronunciation I never heard until recently. This is how Liz Cheney pronounces the word, and everyone I hear on the radio or television seems to be following suit. Is this pronunciation going to become the standard one? If so, why? It really doesn’t seem logical.
