If elections were to be held today, Prime Minister Ariel Sharon would win an overwhelming majority, besting Labor and his former party, Likud, according to a survey in an Israeli newspaper. Sharon would win 33 parliamentary seats, followed by Labor with 26 mandates. Sharon began a political earthquake when he abandoned Likud and formed a new centrist party yesterday called Kadima (Forward). He was joined by 13 other Likud ministers and Knesset members, including former Jerusalem Mayor Ehud Olmert. Likud officials said the new party would be a "true centrist party, from every perspective: political, economic and social.”
