I continue to disagree. Other articles demonstrate that it is entirely possible to have readable, easy-to-use tables with sufficient numbers of columns to display results for all the parties under discussion. They also show techniques to deal with parties sometimes being reported and sometimes not, and sometimes being reported together. There is no need for the opinion polling table to be so abbreviated. Thus, we should reflect what the citations say. If polls are released that lump everyone other than the four biggest parties as "other", that's fine  we report "other". If polls are released that give results for the Greens, BNP etc., then we should report those. We should be doing our best to avoid a situation where we are in danger of original research: I understand the 'cliff edge' argument, but that approach should be a last resort. We should take our lead from reliable sources, as always.
The above IP user's further comments about the Israeli and Italian elections are erroneous on multiple accounts, but largely tangential to the discussion here.
