Problem: To vote in a SecurePoll election, you need to be redirected to votewiki (vote.wikimedia.org). This leads to potential vulnerabilities (see phab:T298849) and it also requires the interface language of votewiki to be changed based on the language of the local wikis who are running an election there at each given time.
Proposed solution: Refactor the code of SecurePoll to properly use CentralAuth and SUL, so that users don't have to leave their local wiki at all to vote.
Who would benefit: Wikis that hold elections using SecurePoll (currently enwiki and fawiki, soon to include zhwiki and more).
