In practice, two parties are in the fight for the post of Chancellor and the government, although they will both be dependent on forming a coalition with other parties.
It is about the Social Democratic SPD with Olaf Scholz at the helm, who is up against the crisis-democratic governing party CDU's Armin Laschet.
The SPD has recently had a head start in opinion polls, but the distance has shrunk as election day approaches.
In the TV channel ZDF's latest survey, the SPD received 25 percent, overshadowed by the CDU at 23 percent.
- It is very exciting, it is only two meager percentage points that separate them.
The CDU has keyed in all the measurements during the week, says Christoffer Wendick, SVT's reporter on site in Germany, in Morgonstudion.
Many insecure voters
In addition, many German voters, just over a quarter, have not yet decided which party to vote for.
Something that makes it even more uncertain who will be the election winner after the vote count on Sunday.
- We also know that one of the largest groups in this quarter is former CDU voters and it is mentioned as a hidden potential, says Christoffer Wendick.
"May take to the finish line"
It may be some time before it is clear which party will be the largest and who will succeed the longtime Chancellor Angela Merkel.
- It may be that we have to take to the finish line, says Christoffer Wendick.
