Comparing the Zodiac Sun Signs of the 42 USA presidents is interesting (and how many would have guessed Scorpio is tied with Aquarius for first place), but the comparison USA presidents Midheavens proves to be much more striking.
Of the 42 USA presidents, there are unfortunately only 24 where we can be reasonably certain we have the accurate time of birth necessary for the calculation of the Midheaven. Of those 24, approximately 30% (7) have (had) their Midheaven located in the Zodiac sign of Cancer. For those unaware, the USA's birth Sun is located in the sign of Cancer.

Those seven USA Presidents include Chester A. Arthur, William McKinley, Woodrow Wilson, Harry S. Truman, John F. Kennedy, Jimmy Carter, and Bill Clinton.

Just proves that the best Presidents for America have been Aquarains "Abraham Linconn, Franklin D Roosevelt, & Ronald Reagan. Except one "John F Kennedy" but then again he is an Air Sign too.

& if u see Fixed sings are in first place with 17 presidents. & Water signs lead with 13 presidents. But It is something i have come to notice that Water Signs & Air Signs are somewhat very important for the welfare of each other.  

Don't know who will be next president, but it either has to be a Scorpio or an Aquarian if the country has to go forward, or they will lose the No.1 position to either India or China in say 15 to 20 years max.

Interesting! The USA has had a lot of great leaders in the past ( a lot more than some other countries have ) and one of the ones I really admire is Abraham Lincoln. It is great to look at his chart..pretty fascinating I find..

so water sign presidents are the most:)

Leo is the dictator/King and I'm always looking at the Leo factor of those aspiring to higher office.  And you also have to look at the wives.  Ronald Reagan had zilch aspirations for higher office, from what I've read, and it was Nancy who was the driver behind all that.  I've also been observing the Sun signs of Presidents and it's interesting that in the last century, it seems like voters are increasingly driven to vote in those heavy with air.  Yes, Clinton was a Leo but let's not forget his Venus and Mars in charm-the-pants-off-of-you, luxury-loving Libra.  And couple that with his Mars in ever-so-charming Tauraus.  Even though Bush is a Cancer sun sign, I see him more as a princely Libra (his moon).  And before clinton, we had that airy Bush with that very airy Dan Quayle, and then there was airy Reagan, then that airy Libran Carter.  Maybe Hillary will come along and break this love of heavily air types for President.  Some strong water would be most refreshing, historically, and Hillary has more than enough water.
