Is there any way to see how voted for a tag synonym after the voting is over? @gung @Glen_b @StephanKolassa @Scortchi. I cannot find any. This is strange, because for other voting (e.g. voting to close) one can usually see who voted. I think I looked everywhere but maybe there is some "hacky" way to get this info.

Not that I know of, @amoeba. (I assume by "how" you mean who.)

@amoeba I have created and approved a great number of synonyms, but have never encountered any interface to peer back into the history. The closest I can come is a record of who originally suggested each synonym.
