Granted we do not have many results in the US (maybe ballpark 200k+ results in last 6 months), still you should be able to find some results in your area.
Sample size is only a tiny part of the relevance of a sample. You can take a thousand gallons of water to test water quality, but if all of it is from the same faucet the sample isn't representative.
Most election/political polls use far less data and very big decisions get made because of them.
