In a survey conducted for ABC News and Altinget ahead of the election that begins on Sunday, only 13.4 percent of those surveyed say they will vote for Høyre. This is a decline of 2.4 percentage points from August, and the lowest figure in this survey since 2009.
Many of the voters are believed to go to the populist Fremskrittspartiet (FRP).
Høyre fails to stop the flow to FRP, which has a loyalty level of as much as 92 percent, says Martin Stubban at the polling institute Opinion to the news agency NTB.
Within the margin of error
That FRP has such a large proportion of voters who cannot imagine voting for anything else is, however, at the same time an uncertainty factor.
It is a strength but also a risk, since many of FRP's voters belong to groups with low voter turnout, says Stubban.
Much also depends on how it goes for smaller support parties. Most changes are within the margin of error, but in the latest survey, Kristelig Folkeparti, which Høyre would need support from, is still below the four percent threshold.
Venstre, which despite its name also traditionally belongs to the right-wing bloc, is doing better and is expected to enter the Storting.
The Green party doubles
However, the party that moves forward the most in the survey is the Green party MDG, which can become a support party if the current Social Democratic Prime Minister Jonas Gahr Støre can once again form a government. MDG is at 7.0 percent, an increase of 3.8 percentage points, the survey's fourth largest party.
The largest is Støre's Arbeiderpartiet at 26.7 percent, followed by FRP at 22.4 and thus Høyre at 13.4.
The margin of error is stated to be 1.0–3.0 percentage points.
