Ahead of Germany’s election this Sunday, Chancellor Angela Merkel’s conservative Christian Democrats are short of the support needed to form a centre-right coalition with the liberal Free Democrats, according to a poll published by Forsa.The CDU and its Social Democrat rivals led by Vice Chancellor and Foreign Minister Frank-Walter Steinmeier are determined to campaign up to the last minute, to convince undecided voters. The Chancellor is hoping to pull ahead with the business-friendly Free Democrats under Guido Westerwelle. The poll put the CDU at 33 percent and the FDP at 14 percent. That together equals the Social Democrats, Greens and Left party combined score. Steinmeyer, however, has said he would not band together with the left. So, another CDU-SPD grand coalition is a possibility. The new government, whatever its stripes, will need to ensure that Europe’s biggest economy, which emerged from a deep recession in the second quarter, continues to grow. The ballot boxes are ready.
