Well... a government party blocking elections, or a single opposition party doing so while doing bad in the polls would be such a bad situation. But what we have here is an ex-member of the ČSSD (IIRC one of the traitors who supported the Topolánek government) being the culprit for blocking (and indeed it looks bad on him: he does it because he won't be re-nominated); and the ČSSD and the KSČM saw the latest attempt to go around him as futile and gave up. (Which was back in September BTW; and was at a time ČSSD led the polls but was in a slow decline from 29 to 28% lasting until the end of the year when they jumped back; see polls here.)
