@Delph: A lot of Poles told me campaign is to start in September. All candidates are not even registered so how can some already be campaigning?
I don't think there's any rules on the official start of campaigning - the September start is based purely on when the two big parties will have agreed to start properly as it's after the summer holidays.
Kopacz and Szydło have been on the campaign trail for weeks now, as has Petru from NowoczesnaPL.
@Delph: Sejm shall be closed all month of August so the current governement does not have 3 months to get things passed. Futhermore AD becomes president on August 6 and obviously he would put his veto to anything.
I think they can still recall the Sejm if they want, although I suspect that PO will be quite happy to let Duda make a fool out of himself in the first month or so without their help.
If he does veto anything, it's like manna from heaven for PO. They'll be able to portray PiS as "same old, same old" - and it will hurt them. Duda's best bet is to work with PO and not to do anything that might arouse any attention whatsoever.
PS: who pays for the PO's campaigning? PO or the Sate (= taxpayers)?
Mix of both, as far as I know. I think one of the referendum questions is about abolishing state funding of parties?
