I'd never seen, nor even considered looking at, natal charts for the two political parties... until this evening..and only because you made it so convenient.
At first I got a bit wide-eyed as to the chart axis for both charts and then realized these charts are "Sun Charts", that is to say cast for noon on that day the Parties were known to have been founded.
The Asc. for the Democratic Partys' natal chart is the 30th of Leo and so is Donald Trump's Asc. ...and has quite the Sabian Symbol, [ibid.] "AN UNSEALED LETTER", which goes to explain a lot as to why Trump seems to never run out of something to say [it also happens to be the location of my Part of Astrology and goes to illustrate why I freely share all my findings and have never charged a dime for any astrological consultation I have given anyone at their request.]
The I.C. for the Republican natal chart is in the 28th degree of Capricorn and the natal placement of the USA's Pluto is in the 28th degree of Capricorn..although the Republican Part was founded about 73 years after the birth of the nation, so a tad more than one degree should be added to all USA natal positions as so to make rectification for the Sidereal precession that transpired in that time. While the Democratic Part was founded in May of 1792 which was 15 years and 10 months after and so 0* 13' 17" needs to be added to the USA natal positions for synastry comparisons.
Here's a list of what I could find of significant relevance without adjusting for the Sidereal precession...so it will be mostly about the Sabian Symbols being shared as for the Republican Party natal chart in synastry with that of the U.S.A.,,, and for the Democrats', 13 minutes of a degree difference isn't anything to fret about.
The Republican Partys' natal chart:
The Moon at 25* Scorpio 40' 20" is conjunct the USA's natal Part of Fortune at 25* Scorpio 40' 42"[and Bernie Sanders natal Asc., if that is reliable birth data for Bernie?]
Pluto at 03* Taurus 35' 55" is conjunct the Part of Surprise [aka Part of Homosexuality..which I have serious doubts that it is] at 03* Taurus 29' 41" and also conjunct the Part of Play 03* Taurus 50' 01"
Mars at 28* Virgo 40' 52" is conjunct the USA's natal Part of Faith/Trust at 29* Cap 10' 32"
Chiron at 18* Cap 53' 23" is conjunct with the USA's natal Part of Father aka Part of Advancement at 19* Cap 10' 57"
The Democrat Partys' natal chart:
Mercury at 26* Taurus 02' 10" is conjunct the USA's natal Part of Individuality, which I rather recently came up with the alternative title, the Part of Surety, as for the reason that the formula by which is used to derive this Part is the opposite of that for the Part of Catastrophe, anyways that USA Part is at 25* Taurus 14' 55", so the conjunction is one by orb of less than one degree.
Here's a dusey, Saturn at 25* Aries 55' 33" is conjunct the USA's natal Part of Innocence, aka Part of Naivete, aka Part of Lawsuits, which is at 25* Aries 06' 55"
The South Node at 02* Aries 13' 17" is conjunct the USA's natal Part of Influence/Magnetism, or at least that is what it has been labeled as to date. It is found by Asc. + Pluto - Moon, and I've never gotten around to doing any research on the Part...so, who knows what it truly is as I doubt that it is about "Influence" or "Magnetism" as for the Moon being the "Trigger" to the Significator, which is Pluto...sounds like the emotional being triggering transformation and possibly death...?
For some reason I'm getting a mental image of a menopausal woman with a 44 magnum in her hands... not good, not good at all.
The S. Node is also conjunct the USA's natal Part of Benevolence at 02* Aries 45' 15"
Now here's something I think is special. Mars at 17* Virgo 55' 33" conjunct the USA's natal Part of Soul/Spirit at 17* Virgo 18' 24".
...and lastly, one that I find to be a bit troubling to my mind...Uranus at 15* Leo 04' 11" conjunct the USA's natal Part of Army/Police, aka Part of Surgery [but for a mundane chart I would rather have to think it'll be about the former] at 15* Leo 23' 23"
i WILL ADD ANOTHER OBSERVATION IN ANALYSIS AT THIS TIME AS TO PETE BUTTIGIEG'S NATAL CHART AND HOW IT WILL BE AFFECTED BY TRANSITS THIS COMING NOVEMBER.
Where as Donald Trump has those transiting Nodes perfectly jibing with his own natal Nodes, Pete, on the other hand, will have some serious Nodal problems.
Pete's natal S. Node is at 22* Cap 27' 11" and on election day, November 3rd, of this year [at 8:00 A.M. EST] Jupiter will be at 21* Cap 24' 21", Saturn will be at 26* Capricorn 21' 23", and Pluto, whoo-boy PLUTO will be at 22* Cap 42' 28"
The Jupiter aspect is about differences with current cultural trends. The Saturn affect usually leads to one becoming for the duration, or at least being perceived in that manner, anti-social and even reclusive. With all his planets in the Northern Hemisphere of his natal chart...that's sort of what He already is.
The Pluto aspect causes rejection, or to look down upon, traditional cultural standards and mores of society.
Jupiter is in conjunction aspect all the remainder of this year. Saturn is in aspect currently but moves off around March 4th but it comes back in conjunct aspect in retrograde July 24th, then goes direct again on September 29th, at 25* Cap 20' and doesn't go beyond six degrees until December 1st...but OMG PLUTO, Pluto goes direct on October 4th at 22* Cap 29", which is about as conjunct as a thing can get.
Pete picked the wrong time to run for the Oval office and it may even do long term damage to his political career. If I was in a position to give Him advice, I'd tell him to drop out right now and don't look back. ...besides, He's too dang young to be taken seriously for the Oval office as of yet...maybe in about another 16 years... but I probably wouldn't vote for him then either...as for the reason ... uhhhh....
There's a lot of reasons, period.
