Democratic Senator Barack Obama has continued his series of victories in the party primaries in the US Presidential race.
Mr Obama won the state of Hawaii and the mid-western state of Wisconsin, giving him ten straight wins over Senator Hillary Clinton since Super Tuesday.
Republican Senator John McCain won his party's primary in Wisconsin, using his victory speech to attack Mr Obama's message as 'no more than an eloquent but empty call for change'.
Barack Obama beat Senator Hillary Clinton in Wisconsin by a margin of 15 points, adding further momentum to his campaign.
He is already ahead in terms of delegates needed to secure the Democratic nomination.
Mr Obama also gained support amongst women voters and blue-collar workers.
Speaking before a crowd of 20,000 in Houston, Texas, Senator Obama told his supporters they were the 'party of tomorrow'.
His victory puts more pressure on Senator Clinton to perform strongly in Texas and Ohio, two big states which vote in two weeks.
