Which groups of the Czech population support regressive and xenophobic policies and why?

Czech social democratic Prime Minister Bohuslav Sobotka recently brought about a political crisis in the Czech Republic when he demanded the resignation of his government coalition partner, Finance Secretary and powerful populist oligarch Andrej Babiš, allegedly for his unethical financial transactions. Critics pointed out that the main reason why Sobotka did this may have been his fear that Babiš and his semi-authoritarian ANO movement could win the Czech general election in the autumn of 2017 - the electoral support for Sobotka's Social Democrats is decreasing and the support for Babiš's ANO had been rising.

The extreme right-wing, xenophobic Czech President Miloš Zeman has refused to dismiss Babiš from his government post, in spite of the fact that the Prime Minister has instructed him to do so, thus infringing the constitution. In the meantime, Sobotka and Babiš made an informal compromise agreement, Babiš has resigned and has had himself replaced by another person from his ANO movement in the post of Czech Finance Secretary.It is evident that there is an informal alliance between Zeman and Babiš, but who in the Czech Republic supports it and what will happen in the future?
