Why got so many people running in Batu?

Siti Kasim also wanna run there and kacau, and I've seen posters from Warisan in Batu also.

I guessing they all banking on PKR to field Tian Chua and they think the fella gonna get rejected by voters angry that he usurped the Prabakaran guy.

I'm hoping Praba stays, its been nice having a young fella around and from talking to my friends in Batu area he seems to be around and proactive (eg went on the ground during the covid lockdowns in nearby areas etc).
