The next Palestinian Authority president could be a Hamas Legislator.
If Abbas decides to forgo the chairmanship before the elections take place, his successor by default is speaker of the Parliament – Hamas lawmaker Aziz Dweik.
Dweik, 59, is not slated to run in the elections as a Hamas candidate. The likely candidate would be Isma’il Haniyya, the current prime minister of the de facto Hamas government in the Gaza Strip. But the very notion of a Hamas leader heading the Palestinian Authority is in itself a symbolic victory for the Islamist movement, and a hair-raising option for Israel and Fatah.
The Palestinian Central Elections Commission announced on Thursday that it did not have the capacity to hold elections on January 24, as originally planned, effectively postponing the elections indefinitely.
How would Fatah respond:
A Hamas figure in power is certainly not something that Fatah would take lightly.
“You’re talking about a rival from a party which carried out a coup in Gaza, a party that is refusing to sign the Egyptian reconciliation paper that Fatah signed,” Dr Milhem said. “So you’re talking about conceding to Hamas. For Fatah this is not acceptable at all.”
Actually, I think it was Fatah that held the coup, not Hamas.

Actually you are correct. The Bush Administration tried to pull a coup on Hamas after their election in 2006. This was covered by Vanity Fair in detail here:

seems like everything that Bush and his cronies touched, backfired and had the opposite of its intended effect.
