“I do not know if the people of the United States would vote for superior men if they ran for office, but there can be no doubt that such men do not run.”
― Alexis de Tocqueville, Tocqueville: Democracy in America
We need to choose who holds an office, not pick from those who crave it at all costs regardless of which party you side with. If an existing POTUS needs to campaign for his job at the end of his first term is he worthy of re-election? And why on Earth would a POTUS save political capital till their last term instead of doing what they are elected to do on day 1, its not like they are not set for life after wining the first time.
