This is the result of an election that saw populist Alternative for Germany (AfD) rise and the Social Democrats, led by Soros-stooge Martin Schultz, fall.
Now the Free Democrats (FDP), led by Christian Lidner, understand just how strong their position is. They don't have to make a bad deal with Merkel to get a seat at the table only to have to share it with the ideologically-opposite Greens. They can force a re-vote, see their standing rise, along with AfD and go for a far bigger piece of the pie.
But, ultimately, if Merkel's CDU/CSU coalition party is to stay together, and there's no guarantee of that anymore, it will have to dump Merkel herself if it wants to survive as a voting bloc.
Moreover, the CSU, led by Bavarian Governer Horst Seehofer, could break off from the CDU making any kind of coalition building impossible without a re-vote.
