Political polls continue to show broadening support for the main two Czech left-wing parties, the Social Democrats (ČSSD) and Communists (KSČM), and give them a majority in the Lower House. But that creates a pretty big dilemma for ČSSD leader Bohuslav Sobotka, who is prevented from party rules from forming any coalition with the party to his left even if there may be no real alternative on his right. The low risk of relying on “silent” Communist support also carries its own hazards.
