Polish state budget by VAT fraudsters during that election campaing - was it a lie, too?
No, it wasn`t a lie because fraudsters existed both during Tusk`s and PiS` rules.
However, PiS lied that VAT fraudsters were somehow connected with the rulers and working on their orders. It was a lie coz later nobody was accused and brought to court.
so how come people believed in that lie if it wasn't true at all
We aren`t discussing if sb believed or not. We are discussing the usage of lies in order to grab power. PIS lied in multiple ways and it had allowed them to win the elections until 15th October.
as far as I can remember "Poland in ruin" was not the main motto of PiS parliamentary campaign in 2015
So your memory is quite selective. I remember PIS` TV ads and politicians exploiting that slogan ad nauseam. That is why I considered it amasssing when PIS declared the economy was thriving under their rule only about 2-3 months after they had created the new gov.
