Is Sojourner Truth a democrat or republican?

Answer 1

I'm not sure the question is meaningful. Sojourner Truth lived at a time when women could not legally vote in the US, so it's not clear that she ever had an opportunity to officially join either party. (She did attempt to vote in the 1872 election, but was turned away.)

That said, she was almost certainly Republican in her leanings, since that was the party of Abraham Lincoln and Ulysses Grant, both of whom she visited during their term as president.
