Here is my general assesment...
PML[N] PPP ANP JUI (maulana) forward blocs of PML[Q] lota, excluding that of nilofer FATA seats JI lawyers community overwhelming majority of the people
vs
PML[Q] lota league MQM Sherpao/Shiekh Rashid Party Pagara Group Some legal aids of the prez, including attaaaarni general qayum and kasuri Supreme Court (PCO judges) Some renegade PPP members, primarily McDoom Fahim Some western powers
Looks like a pretty even contest, if you disregard the parliamentary numbers.
edit: JI just said it will support impeachment
why waste the time on these keeray maokray..the two most important groups in this situation are
US and Pakistan Military. baqi sab group aik taraf, these two groups aik taraf and they will win.
