I am not at all active in politics like you seem to be, but it's really easy to figure out which polls lean Republican.
Yes, democrats tend to be doom and gloom but I get these sunshine sites popping up on my facebook and Twitter and you sound just like them now. Most of the people in this forum including me predicted a Clinton victory in 2016. However, I thought people were too confident in assuming a victory and guessing 350+ electoral votes even though the late polls were suggesting that Trump had a decent shot. I am not falling for that. Harris has a very good chance to win, but I am not really confident.
