If the PML(Q) of the 2008 elections can be considered more or less the same as the PML(Q) that ran in the 2002 elections under military rule, it actually did about as well–in votes–in these elections as it did under less competitive conditions then: 25.7% in 2002, 24.0% in 2008.
In 2002, given different district-level competitive dynamics, this quarter of the vote translated into a quarter of the seats, compared to the 14% it got in 2008.
With the “democratic” parties fully participating again, voter participation was higher in 2008, but not dramatically so: about 31 million, compared to 29.6 in 2002.
So, with a slightly higher turnout Musharraf’s party experienced almost perfect stasis in the vote share. It did, however, suffer a substantial loss of seats.
