A poll conducted for German public television station ZDF shows support for Chancellor Angela Merkel's alliance of Christian Democrats (CDU) remains at 36 percent. Her preferred allies, the pro-business Free Democrats (FDP), polled 13 percent, one point down from last week.
Their combined support of 49 percent is more than the three main left wing parties – the Social Democratic Party (SPD), the Greens and the Left Party – can muster, but it still falls short of the outright majority needed to guarantee a governing coalition.
The ZDF survey, released on Friday, showed that Foreign Minister Frank Walter Steinmeier's Social Democrats gained two points since last week to poll 25 points. However, this was partly at the expense of their preferred partners, the Greens, who lost one point to poll 10 percent.
The Left Party, with which the SPD refuses to enter coalition, polled the same 11 percent as last week.
On Thursday, a survey for the other German public broadcaster, ARD, gave the SPD slightly more support at 26 points, but mainly at the cost of the other left-wing parties.
Steinmeier gains ground but Merkel still in the lead
In the stakes for preferred chancellor, the ARD survey showed Steinmeier gained an impressive seven points over last week to poll 30 percent.
However, that is still significantly behind the incumbent. Although she lost two points over last week, Merkel still polled 52 percent, a clear lead that shows the chancellor is far more popular among Germans than her party.
The ARD poll revealed a murky picture for potential coalitions. A coalition of Christian Democrats and Liberal Democrats enjoyed an approval rating of 48 percent, but also polled a disapproval rating of 50 percent.
Persisting with the current uneasy left-right alliance of Christian Democrats and Social Democrats received an approval rating of 45 percent and a disapproval rating of 53 percent.
Meanwhile, a quarter of German voters remain undecided about their voting intentions.
Overall, the figures suggest Merkel is most likely to remain chancellor following the election on Sept. 27. Her preferred option of forming government with the Free Democrats still appears slightly more likely than not, but Steinmeier's SPD is clawing back support and could prevent Merkel from getting her way.
