This is because, political pundits here believe, Trump despite having the largest number of delegates (845) in his kitty is still far short of the magical figure of 1237 delegates he needs to have before the Cleveland convention in July to become the Republican presidential nominee.
Trump, a real estate tycoon, is now eyeing at the Republican primaries next Tuesday in the States of Maryland (38), Pennsylvania (71), Connecticut (28), Delaware (16) and Rhode Island (19), where 172 delegates are at stake. Latest polls indicates that Trump is leading in most of these states.
The entire strategy of Trump's two remaining rivals Senator Ted Cruz (559 delegates) from Texas and Ohio Governor John Kasich (147) is to prevent Trump from hitting the target of 1237 delegates. Both of them are unlikely to cross this mark.
By doing do, the Cruz and Kasich campaigns hope that given Trump's rhetorics and his antipathy with the establishment, the delegates would vote against him thus opening up opportunities for them.
Clinton, who was the former First Lady, former New York Senator and former secretary of state, would thus be the first woman presidential nominee of a major party in US history.
Clinton now has 1,428 delegates from the primary elections and another 502 super delegates, who are mainly party officials, have pledged their support to her. But they can change their vote even at the last moment.
However, with pledged super delegates, her total is 1930 and she needs 2382 delegates. Her sole rival Senator Bernie Sanders has won 1151 delegates during the primary season and has support of just 38 super delegates.
Latest polls show, Clinton is leading in most of the Democratic primaries to be held in states of Maryland, Connecticut, Delaware, Pennsylvania and Rhode Island.
