All eyes are on tomorrow's Democratic debate in Las Vegas. While Nevada's inclusion on the presidential primary and caucus calendar is an indication that more attention will be placed on the West, the real attention will be on Hillary Clinton and whether she can regain her balance. In the Democratic debate held two weeks ago in Philadelphia, Clinton found herself the subject of a barrage of criticism not only from her fellow Democratic candidates and moderator Tim Russert, but for her somewhat contradictory answers to questions about drivers licenses for illegal immigrants and the fate of her papers while she was First Lady that are still in the hands of the National Archives. Her performance in Philadelphia once again raised the questions of inevitability and electability. Meanwhile, new polls in Iowa show a tightening of that state's caucus, now just 50 days away. While Clinton has a substantial lead nationally, the latest CBS/New York Times poll shows the Democratic contest in the Hawkeye State neck and neck and neck among Clinton, John Edwards and Barack Obama. On the Republican side, Rudy Giuliani continues to lead nationally. The GOP news in Iowa is not so much that Mitt Romney leads there — that's been the case from the beginning — but that his closest opponent appears to be Mike Huckabee, the under-financed former governor of Arkansas.
