What do Karnataka’s past trends tell us about these elections?

Karnataka will vote in a single-phase election on May 10, with results announced on May 13. Four charts show that the Janata Dal (Secular) is a formidable third party, but the major contest will still be between the Congress and the BJP. Most constituencies are not three-cornered, and the BJP could change the tripartite but not triangular nature of the electoral competition in the southern part of the state.
