Why should a Democrat with wildly different ideology support McCarthy for speaker, especially in light of his bad faith such as raising a spurious impeachment inquiry against Biden? Why should they believe that voting for a speaker opposed to what they believe is best for the country is best for the country? This is a failure of government and unity within the Republican party. If there is some moderate that could form a coalition between the parties, great. Wonderful. Let them be speaker. But no Republican has tried (or at least, no one has gotten even a single vote across party lines). This clown show does not enhance the image of the Republican party, instead lessening it. It only heightens the image of the ultra-conservative because their base is not rational and doesn't recognize that any result will be touted as a win.
