Hillary Clinton enjoys a lead among women, Hispanics, immigrants and all those who Trump has attacked during his campaign.

The contest between the two presidential candidates in the United States is getting tighter and is likely to get nastier as well.According to the latest Reuters polls, Hillary Clinton leads by 10 points against Donald Trump with 44.3% voters saying they would vote for her compared to 34.7% saying they would vote for Trump.Similarly, a CBC poll suggests that Hillary Clinton will get 48.9% votes over Trump's 44.9% votes, if elections were to be conducted now.But it's the electoral college that matters the most; each state is worth a number of electoral college votes equal to the number of members they have in Congress, meaning that larger states are worth more votes.The number of electoral college votes needed to win a majority is 270. ABC projection suggests that Clinton would win 332 electoral college votes if the election were held today. Trump would get 206.But for now Trump has more to worry about than Clinton, while the Democrats are rallying behind Clinton staunchly, Trump has an uphill battle, with Republicans publicly disapproving his comments.Both sides are poised to start a fresh flurry of negative ad campaigns as the fight gets tighter. Pro-Clinton super PAC is now launching a 'Trump Lies' campaign - and Donald Trump is likely to hit back.But Clinton enjoys a lead among women, Hispanics, immigrants and all those who Trump has attacked during his campaign - but he enjoys support of white collar voters and it could eventually boil down to a few swing states in the race to the white house.On the back of her big wins on Super Tuesday where Hillary Clinton made history by becoming the first woman in the 240 year history of the United States to clinch a presidential nomination, "breaking the glass ceilings'' and ''reaching a milestone'' she seemed confident of beating Trump. "Your efforts have produced a strong majority of the popular vote, victories in a majority of the contest, and after tonight, a majority of pledged delegates," she said.But Trump believed he too has made history. "Our campaign received more primary votes than any GOP campaign in history, no matter who it is, no matter who they are, we received more votes. This is a great feeling."
