This possibility has led to suggestions to Election Commission to change those states with even number of seats, and I have just counted there are 9!
They are: Kedah 36, Terengganu 32, Penang 40, Pahang 42, Selangor 56, N. Sembilan 36, Melaka 28, Johor 56 and Sabah 60! This fact shows it did not occur to the ruling government nor the EC that such a possibility could happen and they never thought about this until now.
On a lighter note, if Pakatan wins the by-election in Kuala Besut, the scale which is used as BN's logo, would achieve a perfect balance! How ironic that when this happens, it creates problems in administration. It actually reminds me of the Cantonese saying, 'Pun kan part liong' or 'Half kati (equals) eight tahils', which is quite close to the English saying, 'Pot calling the kettle black'.
Anyway, according to Husam, PAS will let BN continue as state government if they won this by-election...
