Do you know how meaningless a poll 4 years out from an election is?
Of course it has no predictive power on what's going to happen in November 2020. Yet, many 2020 polls will be conducted in the next few years, and they'll help set the narrative, and may even impact who ends up running. E.g., if Trump has terrible job approval ratings but is still ~even in hypothetical general election matchups with Dems, that'll affect the coverage. If Biden and Sanders lead Trump by double digits while Booker and Warren trail him (whether just because of name recognition or because of real differences in popularity) that'll add fuel to any "Draft Biden" or "Draft Sanders" efforts, and cause some in the media to talk about how the Dems need Biden or Sanders to run.
So I'm curious as to what these polls are going to look like, and am disappointed that we're not getting them yet. Like I said, last time around, we were already starting to get polls by this point.
