A new opinion poll has put Portugal's ruling coalition well ahead of the opposition Socialists in the race for an Oct. 4 general election though falling short of a parliamentary majority and with one in three voters still undecided. Other polls point to a much closer result in the vote, which could test the country's ability to consolidate economic gains after a debt crisis. Analysts say a stable, majority government will be key to maintaining the nascent recovery. The new survey by respected pollsters at the Catolica University, put the centre-right coalition at 41 percent of voting intentions with the centre-left Socialists trailing on 34 percent.
