Senator Joseph Paine: "Let me go! I'm not fit to be a senator! I'm not fit to live! Expel me! Expel me, not him! Willet Dam is a fraud! It's a crime against the people who sent me here - and I committed it! Every word that boy said is the truth! Every word about Taylor, and me, and graft, and the rotten political corruption of my state! Every word of it's true! I'm not fit for office! I'm not fit for any place of honor or trust! Expel me, not that boy!" (pandemonium erupts)

Jefferson Smith: "I guess this is just another lost cause, Mr. Paine. All you people don't know about lost causes. Mr. Paine does. He said once they were the only causes worth fighting for. And he fought for them once. For the only reason any man ever fights for them. Because of just one plain simple rule:... "Love thy neighbor". And in this world today full of hatred a man who knows that one rule has a great trust! You know that rule Mr. Paine! And I loved you for it, just as my father did. And you know that you fight for the lost causes harder than for any others. Yes, you'd even die for them. Like a man we both knew, Mr. Paine. You think I'm licked. You all think I'm licked. Well I'm not licked! And I'm gonna stay right here and fight for this lost cause! Even if this room gets filled with lies like these! (shuffles 'anti-Smith' letters) And the Taylors and all their armies come marching into this place! Somebody'll listen to me." (he collapses)

Jefferson Smith: "There's no place out there for graft, or greed, or lies, or compromise with human liberties. And, uh, if that's what the grownups have done with this world that was given to them, then we'd better get those boys' camps started fast and see what the kids can do. And it's not too late, because this country is bigger than the Taylors, or you, or me, or anything else. Great principles don't get lost once they come to light. They're right here; you just have to see them again!"

Jefferson Smith: "Just get up off the ground, that's all I ask. Get up there with that lady that's up on top of this Capitol dome, that lady that stands for liberty. Take a look at this country through her eyes if you really want to see something. And you won't just see scenery; you'll see the whole parade of what Man's carved out for himself, after centuries of fighting. Fighting for something better than just jungle law, fighting so's he can stand on his own two feet, free and decent, like he was created, no matter what his race, color, or creed... That's what you'd see."

Diz Moore: (into phone) "...This is the most titanic battle of modern times. A David without even a slingshot rises to do battle against the mighty Goliath, the Taylor machine, allegedly crooked inside and out. Yeah, and for my money, you can cut out the "allegedly."

Jefferson Smith: "You see, you see, boys forget what their country means by just reading 'The Land of the Free' in history books. Then they get to be men they forget even more. Liberty's too precious a thing to be buried in books, Miss Saunders. Men should hold it up in front of them every single day of their lives and say: "I'm free... to think and to speak. My ancestors couldn't - I can... and my children will." Boys ought to grow up remembering that."

Diz Moore: "You're not a senator! You're an 'honorary stooge'. You oughta be shown up!" Press Man #1: "Have a drink, Senator?" Press Man #2: "It'll taste better than the truth!" (crowd laughs, Smith starts walking away) Diz Moore: "Hey Senator... Don't let it get you down - a hundred years from now nobody'll know the difference..."
