ISLAMABAD (AP) — Pakistan is holding parliamentary elections this week but many voters are disillusioned and wonder if the balloting can bring any real change in a country mired in political feuding, a seemingly intractable economic crisis and resurgent militancy. Forty-four political parties will compete on Thursday for a share of the 266 seats in the National Assembly, or the lower house of parliament, with an additional 70 seats reserved for women and minorities. After the election, the new parliament will choose the country’s next prime minister.
