You don’t need any math skills to understand politics. All you need to know is how to count. You need to be able to add and subtract, to multiply and divide.
There are magic numbers on politics. I learned all this as a freshman state senator in Alaska. There, the magic numbers were eleven and fourteen. Eleven was a majority, and fourteen was a 2/3 supermajority.
For a President, the most important magic number is 34. If he can retain the support of 34 Senators, he cannot be removed from office, and can serve out his term.
The magic numbers contained in the Constitution were the product of a lot of thought, by men like Madison and Mason. They wanted Congress to be able to rein in a rogue President. But they didn’t want it to be easy.
