"I had never really planned on being a speechwriter." — Jon Lovett

Republicans paint everything that Democrats have been for as socialism, too far to the left, as extreme, and it didn't matter how moderated it was; it didn't matter that Obamacare started out as a compromise. You might as well say what you're actually for and show what you really are.

There is that definition of leadership that says, 'Leadership is convincing people to do things that they otherwise wouldn't have done because you've made them believe it's the right thing to do.' And a great speech can do that.

Because the speech is an argument, and a great speech makes an argument well, the act of making that argument is a really important part of how the policy process coalesces and solidifies both for the candidate and also the people serving that candidate.

Regardless of how lyrical or rhetorically gifted they are in conveying big ideas, any candidate can do a good job of giving a speech if the goal of a speech is more than just delivering it well but achieving some end, whether it's convincing people of some issue or persuading them about you as a person.
