National Presidential Primary County and State Maps (1912-2020)

A fair amount of empty precincts on the Republican side:

Are those Sanders' pockets in Philly demographically notable? As in, are those the Latino areas or the very white areas? Or maybe are those the university areas?

Almost all of the precints that Bernie won is in white neighborhoods. Hillary won every minority neighborhood by a huge margin.

Theres also a pattern that happened in NYC that happened in Philly.  Irish areas less supportive of Hillary compared to 2016 but she still won them like in NE Philly. And the Italian neighborhoods because they couldnt vote for Trump they voted for Bernie and going from strongly Clinton to 50-55% for Bernie in 2016 as a protest vote which happened in South Philly.

Realist, where are you getting your data from Wyoming? You have counties there that were previously believed to be ties to have gone to Clinton or Sanders.

I'm using popular vote data whereas most use delegate totals.

I'm guessing you didn't make this, but have you seen this precinct map by party affiliation for Kentucky yet? Pretty cool. I love the starkness of the county boundaries - tells you why partisan affiliation remains the way that it does, and it's not because of laziness or whatever.

Somehow when I saw it I thought it was a Sanders/Clinton map.

It comes very close to being such, yes.

Official results for New York City 2016 Republican Primary by Precinct.  The NYC Board of Elections released Carson's numbers, so I've included him, too, even if his votes didn't count.  Per the standard Atlas colors, Trump is in Orange, Kasich in Red, Cruz in Yellow/Gold, Carson in Purple using standard Atlas gradation:

Manhattan:


Staten Island:


Brooklyn & Queens:


Bronx:


I've been playing around with CartoDB.com, which is where the maps come from this time instead of my usual MapWindowGIS. There is a  zoomable maps of the winner of each precinct here:
Winner Map.

I also made heat maps for each of the four candidates, showing their percentage in each precinct.  These use the standard Atlas color breaks for the respective colors of each candidate:
Trump
Kasich
Cruz
Carson

I also made two maps of the total votes cast in the Republican Primary.  This more or less correlates with where the white ethnics live in NYC:

Democratic Primary results forthcoming later this week.

Here's the Democratic side in NYC:

Manhattan:


Bronx:


Brooklyn & Queens:


Staten Island:


The CartoDB map is available here:
NYC Democratic Primary

I've also made CartoDB heat maps for Sanders and Clinton percentages, here:
Clinton
Sanders

The total Democratic Votes Cast per Precinct map is available here.  They looks much different than the Republican maps.  Democrats are everywhere in NYC!:

cinyc, is it safe to assume most of that yellow in the Republican map is Cruz? The keys for 10-30% Trump and 50-70% Cruz look very similar.

Yes, the yellow/gold on the map is Cruz.  I probably shouldn't have included the 10-20% colors in the key - it's mathematically unlikely for someone to win a precinct with that low a percentage because there were no write-ins.

You can check the actual vote numbers by clicking on the precincts on the CartoDB map I linked above.  Wincode there is just the color code plus the percentage of the vote received.  (I'm still learning how to use that website - I think I added a legend to the Republican Primary Map that sort of works now).

Choosing orange, yellow and red as the three candidate colors is kind of a bad idea due to bleed, but that's what Atlas has chosen for these candidates.  Blue, yellow and red would have been better, but the field was larger at one time, and Rubio got blue (or was it green?).

very cool, cinyc.

An update on some of my precinct results collecting:

• FL: 66/67
• NY: 43/62
• KY: 110/120
• IN: 40/92
• RI: 5/5 but no shapefile

2016 Democratic Primary in Whatcom County Washington, aka the beauty pageant:

Areas that you have to drive through Canada to get back into the U.S. love Hillary.  (Point Roberts)  I wonder if she won the Northwest Angle of Minnesota  - though we'll probably never know, since Minnesota held a caucus and I doubt there was a caucus location there.

This thread is damning proof that Dave Leip needs to add a like button. Seriously.

Here's a map showing which party had higher turnout in this year's presidential primaries in my home county of Whatcom. Overall, it favored Democrats 57.42% to 42.58%, about a 15% point spread remarkably similar to Obama's margin of victory nearly four years ago.


One note, all the purple precincts minus 267 and 268 (Northwest Bellingham) cast more votes for Democrats than for Republicans. However, exact percentages for said precincts are unknown, due to the fact that Republican tallies were so small that they were not included (Exact language: "* Precincts were consolidated to protect voter privacy." -Whatcom County Auditor)

New York City amended their results last week.  The changes mainly affected Queens, but there were some changes in Brooklyn, too.  I updated the Brooklyn/Queens maps upthread and on CartoDB.

I really didn't see much of a major change, though.  You can compare the old and new maps by searching for Brooklyn in the gallery.

What effect did those changes have? Did Clinton and Trump's leads grow or shrink at all?

Not by much.  

On the Democratic side, Clinton lost 0.05 points.  691 fewer votes were included in the amended count.

On the Republican side, only Cruz lost more than a hundredth of a point - and he only lost 0.011 points.  Trump gained about 0.007 points, and Kasich 0.005 points.  641 fewer votes were counted.

It could have changed the results in some precincts by more - but I couldn't pick any significant changes out when eyeballing the two maps.

[catographer]

Clinton was also on the border of 60% in Brooklyn and Manhattan and bordering 70% in the Bronx. Did she cross any 60%s or 70%s because of the small changes? I'm asking because those are markers on the county-level maps, so it would change how those look.

The Bronx and Manhattan didn't change at all from the "final" official results, and Brooklyn only had a few minor precinct changes.  Most of the (presumably) errors were in Queens.  Here's Clinton's percentage total by borough in to the tenth of a percentage:

Manhattan 66.0%
Brooklyn 59.1%
Queens 61.7%
Bronx 69.6% (rounded up from 69.59%)
Staten Island 53.2%

Jeb! won a precinct in Albuquerque, btw.

Puerto Rico just finalized their results.  Here is a map of the Puerto Rico Democratic Presidential Primary by Senate District:



Vieques and Culebra are in the Carolina VII Senate district, I think.

They also released precinct info, so I might be able to make a map of whatever geography the mega-precincts are from if I can find the PR County shapefile.
