A new poll of likely Democratic voters in Wisconsin shows that Bernie Sanders is very close to taking the lead from Hillary Clinton.

The WPR/St. Norbert poll showed that 47 per cent said they would vote for Clinton, while 42 per cent said they would vote for Sanders, making the margin just five points.

Clinton’s lead in Wisconsin has narrowed significantly since September, when a Marquette poll had her lead over Sanders at 12 per cent.

The poll also found that in general election contests, Sanders overall performs better against Republicans than Clinton.

The poll had a margin of error of plus or minus four points.
