We need a president who knows and understands politics because he knows and understands people and can galvanize them. When he speaks, you listen, in part because you believe he’ll give it to you straight, in part because his views seems commonsensical, in part because something in his optimism pings right into your latent hopefulness, and in part because he’s direct and doesn’t hide his meaning in obfuscation, abstraction, clichés and dead words. …
