CHARLESTON, W. Va. (WSAZ) -- A new tracking poll out late Tuesday shows Hillary Clinton with a sizable advantage among registered Democrat and independent voters in West Virginia over opponent Barack Obama. The poll was completed prior to the decisions in North Carolina and Indiana.

56% of those surveyed indicate they will vote for Clinton compared to 18% for Obama. There are 26% undecided voters, according to the poll of 403 voters by Mark Blankenship Enterprises. Compared to a previous MBE poll in February, Clinton is up 13%, while Obama's numbers haven't changed.

A Rasmussen Reports poll showed Clinton with a 56%-27% advantage over Obama Monday in West Virginia.

The entire Clinton family will be in different parts of West Virginia over the next several days. Hillary Clinton plans to attend a rally at the state capitol in Charleston Thursday morning.

Today, Sen. Clinton adjusted her schedule and will be attending a "Solutions for the American Economy" rally at Shepherd University at noon with her daughter Chelsea.

Former President Bill Clinton will make stops in Phillippi, Sutton, Fayetteville, Lewisburg and Mercer County Thursday.

Barack Obama is also expected to make a trip to West Virginia over the next week.

West Virginia will stand alone in the national spotlight Tuesday, May 13th as the only state to vote.

The MBE poll also looks ahead to the fall election against the presumptive Republican presidential nominee John McCain. Of the Democrats and independent voters surveyed, Clinton shows up better against McCain in West Virginia. 62% of Democrats and independents indicated they would vote for Clinton over 24% for McCain. In a head to head matchup between Obama and McCain in WV, Obama received 37% support compared to McCain's 35%.
