Donald Trump has clear lead over rivals in final poll
HILLARY Clinton is holding onto a slim lead over Bernie Sanders in Iowa as Democrats prepare for Monday's caucuses, according to a highly respected poll. The poll also gives a clear lead to Republican Donald Trump.
The polls by Bloomberg News and the Des Moines Register put Ms Clinton leading Mr Sanders, 45 percent to 42 percent. Former Maryland Governor Martin O'Malley has three per cent in the survey conducted January 26-29.
Meanwhile, Saturday evening's poll found Mr Trump leading Senator Ted Cruz 28% to 23% among likely GOP caucus-goers.
The poll, conducted by veteran pollster J Ann Selzer, also found Senator Marco Rubio with 15 per cent and retired neurosurgeon Ben Carson at 10 per cent
The poll is considered by pundits to be one of the most accurate, based on recent years.
The woman who runs the poll, Ms Selzer, has an impressive track record.
Ms Selzer and her Des Moines-based firm, Selzer & Company, is impressive: Selzer, has polled for the Des Moines Register for decades and was the only pollster to correctly predict the order of Democratic candidates in 2004.
Politico said that her final poll before the 2008 caucuses accurately predicted that a surge of first-time caucus-goers would help push Barack Obama to victory.
She also said former senator Rick Santorum's surge in the waning days before the 2012 Republican caucuses when few others did. Just last year, she pointed to an Iowa Senate race that gave Republican Joni Ernst a seven point lead, contrary to other polls. Mr Ernst won by nine points.
"I think it has to do with being more of a traditionalist, science-based pollster," she told the news website, explaining her remarkable accuracy.
"And because it has worked for me, I've not been tempted to go and try other methods. And because I have clients who are willing to pay the premium that it takes to do it this way, I've not had to cut corners."
