This is post election. They didn't have the majority during the elections, so while it is impressive, it doesn't give them new political powers. Also, they require coalition partners, but nobody is willing to do that. If a coalition can be formed between (looking at the chart) Union, SPD, and Greens, that puts them at >50% giving them a majority to govern.

If the new coalition is formed and they don't get their act together within the time of governance, the next elections could be fatal for democracy in Germany. Honestly, like in most other European countries facing threats to democracy, their current governments must take decisive and quick action to make more people happy. However, current governments are trying to play the nazi's game, and they are predictably losing ground because that's not a solution.

Major parties are playing identity politics, trying to be populistic, bundling nazi ideas as their own, or quite simply not uniting like for example the French left-wing parties did (however short-lived that was). They should be:

• decreasing the gap between the rich and everybody else
• improving EU and national sovereignty by promoting non-US products and services to stop the influx of US and Russian propaganda
• taking radical action to make lodging and life in general more affordable (more social housing, making multi-home ownership less attractive, regulating the market more, etc.)
• improving public transport to reduce car dependence to reduce air and noise pollution in cities, which also makes transport more affordable
• providing more education with paid educational leave to allow career switches
• reduce hurdles for creating small businesses and provide guidance for those willing to start businesses
• invest in technology that makes life easier and more comfortable (better internet to reduce trips to office and government offices in particular, subsidies and research into improved heating and heat retention to reduce electricity and gas bills, ...)

and so so much more. A happy, educate populace is much less likely to be duped and and magnitudes less likely to vote against their own interests (like voting for lying politicians or nazis).
