Maybe thats because in the last 6 years Karchites feel their city has progressed?
I too get the feeling that Musharaf is far more popular with Karchites than say
Punjabis, Balochis, Sindhis, Pashtuns.
I bumped into a handful of people who supported Musharaf out of my stay 9 week stay there. Most people hate him. The only thing they worry about is the chaos it could cause to removed him. they know pakistancant afford.
I have seen only urdu speaking people supporting dictator. Maybe because of his ethnicity.
