US presidential candidate John McCain is expected to visit Israel next week, Ma'ariv reported Sunday. According the paper, the Republican candidate is set to meet Prime Minister Ehud Olmert, Defense Minister Ehud Barak and Foreign Minister Tzipi Livni on his trip. The goal of his visit is reportedly to try and gain popularity among the Jewish community in the US. Meanwhile, Sen. Barack Obama captured the Wyoming Democratic caucuses on Saturday, seizing a bit of momentum in the close, hard-fought race with rival Sen. Hillary Rodham Clinton for the party's presidential nomination. Obama generally has outperformed Clinton in caucuses, which reward organization and voter passion more than do primaries. The Illinois senator has now won 13 caucuses to Clinton's three. Obama has also shown strength in the Mountain West, winning Idaho, Utah, Colorado and now Wyoming. The two split Nevada, with Clinton winning the popular vote and Obama more delegates.
