FDP is member of ALDE, which is the liberal democrats party. They are in a historic low in the polls recently. They are also part of the federal government coalition right now.

The FDP has most of the time been a very small party in popular votes, but are still seen as very established, since they traditionally join a coalition with another larger party (recently mostly CDU/conservatives), and so becoming a deciding factor, more so than their share of the vote would suggest. At the same time they are in most elections in danger of not winning any seats at all, since most elections in Germany have a threshold of 5% as a minimum you need to gain any seat via the proportional vote mechanism.
