Opinion polling for the Turkish general election, November

There are less than 40 days left until the referendum on constitutional amendments that will grant unprecedented power to Turkey's president. But pollsters are having the hardest time in decades on how to distribute the undecided voters or not distribute them at all.

A local research company, which was previously raided by government inspectors after releasing an opinion poll showing Turkey's ruling party losing votes, announced Sept. 19 that its pollsters were detained in Istanbul while conducting a field study.

Three polls recently conducted in Turkey show the Justice and Development Party (AKP) will fall short of the votes needed to form a single-party government in a snap election on Nov. 1.

According to pollster Metropoll?s latest survey, the AKP stands at 41.7 percent of the votes, up from 40.9 percent in the June 7 election.

Turkey's ruling AK Party is seen falling short of the votes needed to form a single-party government in a snap election on Nov. 1 with 41.7 percent of votes, up from 40.9 percent in the June election, pollster Metropoll found in its latest survey. 

A local research company has reportedly been raided by inspectors from the Finance Ministry, two days after releasing its latest public opinion poll showing support for Turkey?s ruling party below 40 percent.
