Who will replace George W Bush in the White House come November?
If there is to be another Republican president, it could well be John McCain, who has swept most his party's primaries and caucases putting the projected total delegates on his side at 1,331, surpassing the 1,191 mark.
Over at the Democrats' camp, however, there is yet to be a clear winner in sight. Former First Lady Hillary Clinton clinched the states of Texas, Ohio and Pennsylvania - giving a huge boost to her flagging bid after her losing streak since Super Tuesday.
The New York Senator and fellow Democratic candidate Barack Obama continue their bitter neck-to-neck race with US media reports putting Obama's delegate count at 1,727, slightly ahead of Clinton's 1,589.
The race for the White House looks set to continue right down to the line with primaries in the states of Indiana and North Carolina each going to Clinton and Obama.
