If calculated from the period of dominance, it has now been almost 15 years since Pakatan Harapan (PH) dominated Selangor since 2008, which was originally named Pakatan Rakyat.

Nevertheless, despite having an outstanding performance, KPI - Key Performance Index which is quite encouraging in Selangor and also acknowledged by political observers, the state elections this time is more challenging.

This is because PH has collaborated with Barisan Nasional (BN) which was once considered as a 'long-time nemesis'.

However, things have changed as per the expression, "There is no permanent friends and enemy in politics".

On that basis, PH, which launched the concept of a Unity Government, made a new history by merging with BN.

Therefore, two large party groups joined forces to maintain dominance in Selangor, the richest state in Malaysia with a fairly advanced and rapidly developing economy - this measure is based on Gross Domestic Product (GDP per capita).

Taking into account PH's performance at the federal level, which is not very encouraging… political analysts previously described PH will face unexpected challenges to maintain power in Selangor in particular.

We also cannot characterise the presence of Perikatan Nasional as ‘persona non grata’ (an unwelcome party) considering the results recorded in GE15 are quite surprising.

This Selangor PRN field will be the measuring stick for the unity government; the ideology of both coalitions between PKR and Barisan Nasional.

The election bells are ringing. The candidates must use this 14-day campaign period as best as possible to appeal for the support of almost 3.7 million registered voters in Selangor through ballot papers that will be casted on August 12th.
