Portugal's politics and elections

[DC Al Fine]

Since you're Portuguese, I have two questions:

1) Could you please explain what the main differences between PSD and CDS-PP? Policies or voters works.

2) Are there any weird features of Portuguese politics that make it unique (e.g. Weird voting system, a demographic group voting in a weird way etc.)

Euthanasia legalization will be voted on 29 May:

MPs will vote to legalize, or not, euthanasia practices in Portugal. At the request of CDS, the vote will be member by member, not by party groups. At the moment, these are the party standings for the crucial vote:

PSD - Freedom of vote (each MP can vote by their own conscience)
PS - Freedom of vote (each MP can vote by their own conscience)
BE - In Favour
CDS - Against
PCP - Undecided
PEV - In Favour
PAN - In Favour

Because of this vote, religious communities in Portugal - Islamic, Jewish, Buddhists, Hindu, Bahia, Catholic, Protestant, Evangelic and Adventists - all signed a common document stating their opposition to the legalization of euthanasia. The document will be sent to the President of the Republic, which will have to decide if he signs in the law, vetoes it or sends it to the Constitutional Court, if it passes in Parliament, of course.

What share of PS and PSD legislators are expected to vote for the bill?
