A new public opinion poll by Washington Post/ABC finds New York Senator Hillary Clinton and Illinois Senator Barak Obama in a tight race for the majority of Democratic voters two days before the multi-state balloting. On the Republican side, the poll indicates Arizona Senator John McCain leads former Massachusetts governor Mitt Romney 48 percent to 24 percent among their party's voters.  Former Arkansas governor Mike Huckabee and Congressman Ron Paul are trailing far behind. Clinton and Obama are campaigning in the West of the country Sunday.  McCain is scheduled to campaign in Connecticut and Romney is in Missouri. At stake Tuesday for the Democrats are more than half of the 2,025 delegates needed to win the party's nomination for the general election in November.  For the Republicans, the 22 state elections and caucuses Tuesday represent the vast majority of the 1,191 delegates needed to clinch the party's nomination. Television host Oprah Winfrey and Caroline Kennedy, daughter of slain President John F. Kennedy,  will join Obama's wife, Michelle to campaign in Los Angeles, California. Former president Bill Clinton will attend headline events for his wife. Meanwhile, Senators McCain and Clinton outlined their positions on the Iraq war in separate appearances on Fox News television Sunday. McCain said al-Qaida will win if troops are withdrawn from Iraq.  Clinton differed saying withdrawing troops from Iraq is a good way to get Iraqi's to take responsibility and to make tough decisions.
