Slovakia Election Update: Pictures worth at least 300 words

I love polling results and I am always surprised and unhappy when they are abused.  Recent articles in SME and Pravda put needless stress on these results by, on the one hand, treating them as unique and absolute indicators of a party’s success or failure (at least until the next one comes out) and, on the other hand, lumping them together into time series regardless of their origin or methodology.  Toward this end, I propose that we fix this by, on the one hand, treating each poll as a unique series which is to be compared to other series, and, on the other hand, when we do lump them together into time series, we smooth them out and look less at individual polls and more at overall trends.  I’ve tried to do both of those things here with some overall coalition/opposition graphs that, I think, speak for themselves in various ways (though that probably won’t stop me from trying to speak for them at some future point.
