Each side bemoans the abuses by the other, but then takes advantage of them when they are in power, and ratchet continues on. Wash; Rinse; Repeat...only we just yell back and forth about the rinse.
This is why we need strong systemic protections, and why a "living, breathing Constitution" sets up a Republic that is destined to fail. The "solution" of just making sure the right people win the election is no solution at all.
But, we won't have third parties until we either eliminate first-past-the-post elections for president, or the president is selected by Congress like the prime minister is selected by parliament. This is one thing we have locked into the system: 2 parties.
