Hillary Clinton has revived her faltering campaign for the US presidency with projected primary election wins in three states.

US media say she has taken the Democratic primary polls in Texas, Ohio and Rhode Island. The results of caucus meetings in Texas are not yet known.

Rival Democrat Barack Obama took the primary poll in the state of Vermont.

Meanwhile, John McCain has won the Republican nomination with projected wins in the four states.

His closest rival, Mike Huckabee, has dropped out of the race and pledged to support Mr McCain's candidacy.

Both Democratic candidates called Mr McCain to congratulate him on sealing the Republican nomination.....
