Portuguese Prime Minister

Which party will the prime minister of Portugal belong to after the election on October 4th?
Portugal Ahead: 15%
Socialist Party: 80%
Some Other Party: 3%
No Stable Coalition will be Formed: 2%

Because of the potential for coalitions in Portuguese politics, the party that wins the highest percentage of the vote may not be the party that ultimately forms the government.  As I noted in an earlier post, the Socialist Party is currently leading slightly in the polls (their lead of about 2% hasn't changed since my last post).  However, even if they don't get the highest percentage of the vote, they are likely to form the government.  Almost all of the minor parties in Portugal seem to be left-wing, and thus better potential coalition partners with the Socialist Party then with the right-wing Portugal Ahead.  Portugal Ahead would have to win almost a majority of the seats to be assured of forming the government.  Given that they are presently at about 35% of the vote, this is a difficult task.
