Is the Prince of Conde also the Prince of Conti? Which prince was the candidate?
Who would be the Elector Palatine who was a candidate?
Conti was a junior branch of Conde, both descended from the Bourbons. The candidate in 1674 was Louis de Bourbon, Prince of Conde, AKA 'Le Grand Conde'. In 1697, one of the candidates was his nephew, Francois Louis, Prince of Conti, AKA 'Le Grand Conti'. History is confusing sometimes, ey?
The Elector Palatine in 1674 was Philipp Wilhelm of the Neuburg branch of the House of Wittelsbach, a son-in-law of Zygmunt Waza. He basically split the French-aligned vote. Dissuade either of these from standing and Charles of Lorraine has significant opposition, not only from the French supporters but also from the so-called 'Piast' party, which favoured a Polish born nobleman. IOTL, they chose Jan Sobieski, but if he dies before 1674 (or whatever your PoD is) then they are obviously going to choose another of their number. The previous king, Michal, was one of their as well. I have no idea who they would pick in the absence of Sobieski, or even (off-hand) who their leaders were, but I would assume that Michal Kazimierz Radziwill would have been a possibility, given his military and patriotic background, wealth, and relation to the now-dead Sobieski. If he stands, his race (he was Lithuanian) will count against him, allowing the throne to go to the foreign guys that you are more interested in.
