Sorry- but online polls are highly biased by self-selection. It’s also a very lazy way to collect data — it certainly can increase the sample size more easily, but only those *already* on that site (immediate indication of bias), & *already* interested enough to take the time to answer the questions (political engagement), & thus, *likely* already interested in a particular candidate and/or informed to some extent about 1 or more candidates (higher information voter) takes the time to answer online surveys. This is called self-selection bias.
