[WASHINGTON] Hillary Clinton's lead over Donald Trump has narrowed since he became the apparent winner of the Republican presidential nomination, according to a national poll out on Friday.
The CBS News/New York Times survey found that 47 per cent of registered voters would support Mrs Clinton, while 41 per cent back Mr Trump.
Last month, the former US secretary of State, in a CBS News poll, led Mr Trump by 10 points.
The same survey gave better odds to Bernie Sanders - Mrs Clinton's rival for the Democratic presidential nod - showing him leading Mr Trump 51 per cent to 38 per cent.
The phone survey of 1,300 adults had a margin of error of plus-or-minus three percentage points, the Times said.
Mr Trump became the presumptive Republican presidential nominee earlier this month, when the last of his rivals dropped out of the race, after he amassed what appeared to be an insurmountable lead in delegate support.
Republican Party leaders hold their convention to formally select their nominee in July.
Mrs Clinton remains locked in a primary fight-to-the-finish with Mr Sanders, but her commanding delegate lead over the Vermont senator appears sufficient to propel her to the nomination when Democratic Party grandees hold their convention, which also takes place in July.
