Start with a meta-review of historical accuracy and transparency, eg: https://www.natesilver.net/p/pollster-ratings-silver-bulleti...
Details on methodology and sample size can be Googled, eg: https://poll.qu.edu/methodology/ , https://www.washingtonpost.com/news/the-fix/wp/2015/07/24/ev... , https://www.google.com/search?q=Marquette+University+Law+Sch..., etc.
Sample size is less important than you might think, due to https://en.wikipedia.org/wiki/Binomial_proportion_confidence...
