KANSAS CITY, Mo. (AP) _ Gov. John Ashcroft and Sen. John Danforth rolled over their Democratic rivals Tuesday to win re-election easily, and George Bush won Missouri's 11 electoral votes after a see-saw battle.

With 82 percent of the votes counted, Danforth won a third term with 948,001 votes or 67 percent and state Sen. Jay Nixon had 461,815 votes or 33 percent.

In the governor's race, Ashcroft had 899,797 votes or 64 percent and Betty Hearnes, wife of a former governor, had 507,876 or 36 percent.

In the competition for Missouri's 11 electoral votes, Bush had 682,996 votes or 51 percent and Michael Dukakis had 653,332 votes or 49 percent.

Democrats who held five of nine U.S. House seats - including one-time presidential candidate Richard Gephardt - easily won re-election.

Republican Rep. Bill Emerson was leading in a rematch with Democratic farm activist Wayne Cryts in southeastern Missouri's 8th District.

Missourians also were asked to decide the fate of the so-called MedAssist proposal, a $296 million tax increase to finance a statewide health insurance plan.
