This is the only priority. Nothing else matters.
I think the underlying polling data is pointing out some clear reasons for Biden having such a large lead nationally at the moment.
1. Biden is polling slightly better with younger voters than Clinton
2. Independents leaners and "soft" repubs vs. "soft" dems. - the indy leaners are leaning much harder for Biden on the Dem side than the indy leaners are leaning toward trump on the rep. side.
Also, same story with soft rep and soft dems. Soft Dems are going for Biden at almost the same rate as regular/solid Dem voters. Trump loses almost 20% from solid Rep to soft Rep.
3. The ones that don't like either candidate. Yes this encompasses a lot of the numbers in the last section. But this is where we see the real, very large shift.
This encompasses about 20% of the electorate. This is from the Cook Political report on May 20th (So BEFORE the protests began):
What I find very interesting is when you go back and you look at the exit polls in 2016, 60% of voters had an unfavorable view of Donald Trump. 60. 54% had an unfavorable view of Hillary Clinton. And you had 19% had an unfavorable view of both of them. And then they voted, though, for Trump by a 20-point margin.
I asked the Quinnipiac people -- they're terrific, by the way -- I asked them today if they could run something to see, okay, of the people that have an unfavorable view of both Donald Trump and Joe Biden, how do they break? And Biden is ahead 49-18 among the people that dislike both of them while they cut by a 20-point margin against Hillary Clinton.
So this group of 20% of the electorate, right now, has swung from Trump to Biden by FIFTY POINTS.
4. Probably the most concerning shift for the Trump campaign is the movement of older voters.
From Vox:
If the (Biden) campaign can win or at least significantly cut into the president’s margins with older voters, a traditionally more conservative and reliable bloc that suddenly seems to be turning away from the president. A recent Fox News poll found voters aged 65 and older said they preferred Biden to Trump by 17 points.
A recent Quinnipiac University poll also showed Biden 22 points ahead with women 65 and older (and Trump leading men in the same age group). These polls could certainly change, but they’re worrying sign for Trump, who won older voters by 7 points in 2016.
“Even if Joe Biden cuts the margin of what Trump won [with older voters], because they’re the largest single age group, it is a huge, huge game changer,” said Biden adviser and pollster John Anzalone.
This group is almost 23% of the electorate. Right now we are looking at a 20+ point shift from Trump 2016 to Biden 2020.
5. Suburban women. I don't have any solid numbers here. But it was a big factor for the 2018 midterm wins. So I'm guessing a decent shift in these numbers. Just overall women of all backgrounds - Trump won in 2016 by about 3-5 points. The latest YouGov poll, Biden was up with women over Trump by about 14 points.
