In the last stretch of the campaign for the Kuala Kangsar (Perak) and Sungai Besar (Selangor) by-elections, we speak to two political analysts about dynamics at the constituency level, in political parties as well as for national coalition politics. We also touch on the Tun Mahathir factor, the Chinese vote and for Sungai Besar in particular, the Selangor Pakatan government factor.
