How reliable are election polls?

Election polls depict the current political mood and are not a forecast for the next upcoming election. Due to the polling method, the margin of error of each party's score is 1.5 to 3 percentage points, depending on the level of the score. For this reason, many polling institutes do not mention minor parties until values of around 3 percent are reached, as it is difficult to make serious statements below this level.

What should you look out for in election polls?

Pay attention to a sufficiently large sample size in polls. This should be at least 1000 respondents. Also pay attention to which institute is conducting the poll and who the clients are. Some institutes tend to rate certain parties too high or too low.
