Vice President Al Gore and Texas Gov. George W. Bush coasted to two more victories in presidential primaries in Pennsylvania and Wisconsin, adding to delegate tallies that were already large enough to clinch the nominations.
In Pennsylvania, with 99 percent of precincts reporting, Bush won the Republican primary with 73 percent, or 470,637 votes.
The remaining votes were shared by his former rivals, Sen. John McCain, publisher Steve Forbes and conservative activist Gary Bauer.
On the Democratic side, with 99 percent of precincts reporting, Gore won with 74 percent, or 517,901 votes, according to unofficial results. Former rival Bill Bradley had 21 percent, or 145,481 votes, and perennial candidate Lyndon H. LaRouche 5 percent, or 32,191 votes.
In Wisconsin's Republican primary, with 96 percent of precincts reporting, Bush won with 69 percent, or 324,796 votes, according to unofficial returns. McCain had 18 percent, or 85,160 votes, and Alan Keyes, who is still running, pulled 10 percent, or 46,673 votes. Forbes had 1 percent, or 5,236 vote.
In the Democratic contest, with 96 percent of precincts reporting, Gore won with 89 percent, or 313,357 votes. Bradley had 9 percent, or 31,083 votes and LaRouche had 1 percent, or 3,580 votes.
Tuesday's results were important despite the lack of drama. Pennsylvania, with 23 Electoral College votes, could be a critical swing state in November. Wisconsin has 11 electoral votes.
Voters in the two states also were electing delegates to the national Democratic and Republican party conventions this summer in Los Angeles and Philadelphia, respectively.
