What is VOX?

I guess you have been reading about the surge of the "far-right" party VOX in Spain.  BBC said this "Spain election: Socialists win amid far-right breakthrough" and The Guardian this "Spanish election: socialists win amid far-right gains for Vox party".
Well... Vox is a populist conservative party.  It got 24 seats out of 350 seats for Congress. Vox opposes radical anti-western feminism, LGTBQ ideology and illegal migration. Vox defends national unity and wants to do away with regional governments, since VOX believes it is dangerous for the national unity of Spain.

Why did it have some success?

-Because in Congress there was not right wing national party.
The "conservative" party PP (Popular Party) left all his ideals related to the protection of heterosexual families, they didn't care about the huge amount of abortions performed in Spain and they don't bother to speak the rise of the amount of transgender minors in Spain and they support the spread of LGTBQ ideology by force in public schools and they suppress freedom of education in schools. In the economic policies the Popular Party supports the encrease of public spending to get out of the economic crisis.
Thus the Popular Party lost more than three million voters and half of its seats in Congress. Vox got 2.6 millions votes.

-Because VOX was labelled as a bunch of extremist and promoted by PSOE (Spanish Socialist Workers Party) and Podemos (a populist leftist party).
Why?  I guess they knew that by spliting right wing voters they could make PP lose. at the same time, they may have scared left wing voters in order to force them to vote for PSOE.  Some polls said that VOX was going to get 34 seats and, even, a piece of fake news said 70 seat. "Mission accomplished".

Fun fact:  PP and VOX got all together 8 millions votes and 90 seats, meanwhile PSOE got 7.4 millions votes and 123 seats.
Why? Spain uses the D'Hondt method to alocate seats, those who get more votes in provinces get more seats than those that they get with a proportional method.
