Final scramble for votes before Ireland goes to the polls

Irish politicians scrambled for last-minute votes Friday, the final day of campaigning in a general election that has become a historic three-way fight for power.

Prime Minister Leo Varadkar, of the Fine Gael party, canvassed in the western town of Ennis while Fianna Fail leader Micheal Martin was in his home city of Cork, in the south.

But the two centre-right parties, who have had a duopoly on power for decades, were facing a stiff challenge from Sinn Fein, whose flagship policy is reuniting the republic with British-run Northern Ireland.

An Irish Times/Ipsos MRBI poll published Monday put the republicans on 25 percent, suggesting its left-wing policies to tackle a housing and healthcare crisis have popular appeal.

Fianna Fail were on 23 percent with Fine Gael on 20 percent.

Varadkar has touted his successful handling of Brexit negotiations, which eased immediate fears that a damaging split between Britain and the European Union could hurt Ireland.

But he was heckled by one woman over the homelessness crisis and confronted by climate change protestors, suggesting voters' priorities lie elsewhere.

"This election is wide open," he told reporters. "It's a three-horse race, three parties, all within shouting distance of each other. It's going to be down to the public." Polls open at 0700 GMT on Saturday but 12 islands off Ireland's west coast began voting on Friday as a precaution against bad weather which can affect the transport of ballot boxes by boat.

The smallest -- Inishfree -- has an electorate of just four.

Varadkar was a key figure in the Brexit talks, which saw London strike a deal with Brussels without having a hard border put up between Ireland and Northern Ireland. An open border was a key plank of the 1998 Good Friday Agreement that largely ended more than 30 years of violence over British rule in the north that killed more than 3,000 people.

But polling ranks Brexit low in public concerns and there is broad consensus among all parties on how forthcoming UK-EU trade talks should be handled.

Eoin O'Malley, of Dublin City University, called Varadkar's decision to call an election one week after Brexit a "miscalculation" as it focused attention on his party's failings.

"Because Brexit was actually happening during the election campaign, they thought that it might put it back up as an issue," he told AFP.

"But really for most people the issues are that they're spending long periods of time commuting to work and can't afford to buy a home and can barely afford to pay the rent."
