That's perhabs the worst election analysis I have ever read in my entire life.
You may not like it, but it's all true and you know it ;-)
But I can imagine that you mostly read "analysis" from the German left-wing media propaganda networks, so you're reading crap every day and election. No wonder you're shocked when reading reality. Sorry, not sorry.
If we're talking about the German public GEZ-paid media (pay for the propaganda or get jailed in the "most free Germany of all time"), yesterday I saw an Analysis of the ARD/ZDF talk Show guests in 2017:
CDU/CSU 29 appearances
SPD 24
Greens 12
FDP 8
Linke 8
AfD 1
Great Democracy we're having. But of course, the German media is totally non-bias - let's get outraged about RT Propaganda! ;-)
Can you please stop calling the major German television networks "left wing"? It's ridiculous. You should review their coverage of the Greek crisis 2015 - it was propaganda all right, but it was pro austerity all the way.
Die Linke is a left wing party - would you really suggest ARD and ZDF support Die Linke?
For sure, they don't support AfD either. But that seems to be your only "proof" for a left bias. Please be serious!
My take is that recent events in Germany and many other countries have produced reactions that defy standard left-right division. There is fighting across the right, when people today are not used to this sort of thing. The CDU and AfD are enemies, but this rivalry does not make the CDU left-wing. Rather, they represent a different set of right-wing interests.
