When it comes to describing someone who has opposed something, the term "voted against" might not always be the most fitting. Luckily, there are a variety of synonyms that can be used to convey a similar meaning. For example, one might say that someone "rejected" a proposal or "opposed" a bill. Other terms that can be used include "turned down," "vetoed," "denied," and "refused." Depending on the context and the tone of the discussion, some of these terms might be more appropriate than others. By selecting the best synonym for the situation, you can convey your stance in the most clear and effective way possible.
