In this election there won't be any % barrier in some countries, but I still haven't seen any poll numbers for small parties here in Germany for example. Everything below 2-3% gets lumped in with "Others" as usual, even though about 0.5% would already get them a seat in parliament this time. This makes voting strategically very difficult, because we have no idea whether any small party could even get in.

I get that there are limits to what you can show in a graphic, but even the source links I checked didn't provide more details. Why is that, and has anyone seen poll numbers for small parties, particularly for Germany?
