Making a thread here in the politics section regarding the 2020 Dem primary partially out of boredom and also to see if we can track where the voting bases of each candidate goes as the election season progresses and as major things happen. This was mainly inspired by the most recent poll out of Iowa showing that one candidate in particular has, effectively, shit the bed.
In a recent Iowa Monmouth poll ( I like to RCP because it aggregates polls that you can follow right to the original poll https://www.realclearpolitics.com/epolls/2020/president/ia/iowa_democratic_presidential_caucus-6731.html ) Two major shifts took place that might fly under most people's radars
With Biden, Warren, Sanders, and Harris are the front runners with double digit support, the first big shift occurred with one of those in the bottom tier of candidates whose numbers took a gigantic hit: Beto O Rourke, who is now polling at <1% in Iowa https://www.monmouth.edu/polling-institute/reports/monmouthpoll_IA_080819/
This is a big deal because previously, Beto was polling at around 6% in Iowa, meaning that he has effectively lost his ENTIRE voter base in the first crucial primary state in the election cycle.
I know 6% isnt much, but seeing how all but 5 candidates are polling under 6% in Iowa right now, Beto just went from possibly breaking out into the upper-tier of candidates to being pretty fucked. If you cant get at least 5% in Iowa, your entire campaign is effectively screwed heading into New Hampshire, and Beto is now effectively in that category..... If you look at second pick voting, meaning who would pick certainc andidates as their second choice, Beto's drop was even harder, going from 8% down to 1% https://www.monmouth.edu/polling-institute/reports/monmouthpoll_IA_080819/
The poll also indicates who may have taken that support, or who at least benefits from it.... Beto dropped around 5.5 points, but the only candidates who made any major gains since April have been Warren (+12%) and Harris (+4%).... Biden's numbers have stayed about the same, and the only other big loser brings us to our second big shift, Sanders dropped 7 points from 16% down to 9%..... Assuming Warren absorbed all of Sanders's support he lost, either her or Harris were the ones who then benefitted most from Beto's dropout in support (assuming that he didn't lose his support to some other candidate, who then also lost just about as many supporters to a third candidate)
With the primaries still months away, it looks like the very left-wing vote is beginning to coalesce around Warren, while more moderate voters from lower tier candidates are starting so shift to Warren as well, or support Kamala Harris instead.... Pete Buttigieg, the next kind of 'centrist' candidate similar to Biden, didn't see his numbers shift at all in the same Iowa poll after Beto bottomed out, which means he might become the next middle-tier candidate to fall apart, since supports of lower tier candidates are not switching to him after they jump ship.
