BERLIN (AP) — With Germany's national election just days away, the latest poll suggests trouble for Chancellor Angela Merkel's coalition despite her own personal popularity.

A survey released Tuesday by the Forsa Institute for Stern magazine and RTL television show Merkel's Christian Democrats with 39 percent — unchanged from last week. But her junior coalition Free Democrats dropped a percentage point to 5 percent.

The margin of error is plus or minus 2.5 percentage points, so Merkel's coalition could still win enough in Sunday's balloting to form a new government. But the results are clearly a warning sign.

The Social Democrats polled 25 percent, the Left Party 10 percent and the Greens 9 percent — all unchanged.
