A poll conducted with a sample that is not randomly drawn and not always statistically significant in size. These polls are often done online and can involve respondents who are self selected.

this above info fit for tracking poll or Benchmark poll.

The information provided is more in line with a tracking poll rather than a benchmark poll. Here's why:

A tracking poll is a type of opinion poll that measures public opinion over time by repeatedly surveying the same sample population. It is typically conducted on a regular basis, such as weekly or monthly, to track changes in public opinion over time. The purpose of a tracking poll is to identify trends and shifts in public sentiment.

In the case described above, where the sample is not randomly drawn and not always statistically significant in size, it suggests that the poll is conducted online and involves self-selected respondents. This method of data collection could be susceptible to biases and may not accurately represent the larger population. However, tracking polls are often less concerned with representativeness as their primary goal is to capture shifts and trends in opinion among a consistent group of respondents.

On the other hand, a benchmark poll is typically conducted at the beginning of an election campaign or a major political event. It establishes a point of reference for subsequent tracking polls by measuring the initial levels of support for different candidates or issues. Benchmark polls strive to have a random and statistically significant sample to provide a more accurate snapshot of public opinion at a specific point in time.

Therefore, based on the information provided, the poll described appears to be more consistent with a tracking poll rather than a benchmark poll.
