When Clark asks Lex why he's running for the state senate he says something along the lines of, "that's like Apollo asking Icarus why he's building wings." Daedalus, Icarus's father, was the one who built the wings and gave them to his son.
At the shooting, Clark hears the gunshot, then turns and sees the bullet, which he then chases after and stops. However, a typical rifle bullet travels three times the speed of sound, leaving very little time (even for a Kryptonian) to have even heard the explosion before the bullet hits its target.
At the start of the episode, Lex mentions that "the nurses' union is key in the 49th." However, Kansas only has forty state senate districts, so there is no "49th" to get any sort of support from, nurses or otherwise.
In the rally at the beginning of the show, Jonathan comes out as soon as his name is announced. In the rally later on in the show, he comes out about ten seconds after his name is announced.
As hot as that fire was, the damning evidence on the Kents Lionel lights up never actually burns up. Even at the last second of the shot, the paper is completely whole, and still white, despite the fact that it has burned for a good while.
Forget the stress of a campaign - Jonathan is hit twice with a baseball bat and hung upside down for an extended period. If his heart was any kind of an issue, it'd be in overdrive then shutdown from that kind of treatment.
So why is Martha so comfortable with Lionel? She knows he set up the body-transfer scheme with Clark (and attacked her family, and was ogling her while he was in Clark's body). Plus she knows he tried to kill his own parents, and Chloe, and Lex. Does she really think Lionel is remotely trustworthy?
Why does Lex turn his back on Samantha when she is obviously crazy, what with the head shaving, and capable of violence, knowing what she did to Mr. Kent?
Jonathan does not give the same speech at the start of the episode as he does at the end. In the first version, he goes from saying how his family was surprised by his decision to about how they did not understand in the same shot. In the later version, after he mentions their surprise he goes on to talk about how his son inspires him, goes on for a good long time while the action with Lois is taking place, and then starts to mention his family not understanding.
While the bullet going through the balloon makes for an interesting special effect, it also means that the shooter's view of Jonathan would've been completely obscured by the balloon, as everything but Clark and the bullet were frozen during the sequence.
Trivia: It's confirmed here that Lex and Jonathan are in a state senatorial race. Although it seems rather small potatoes for Lex...
Lionel: I'm always here for you, Martha.
Lionel: How does it feel, Lex, to have people worship you?
Lex: Being the idol for a cult of psychopaths isn't exactly a power trip, Dad.
(Clark comes to the rescue)
Lois: Don't sweat it, Smallville - better late then never!
Chloe: Lex Luthor going "Godfather" on your dad? I don't know, Clark - Lex seems like the kind of guy who lives for the fight as much as the victory.
Samantha: You're losing your edge, Lex.
Lex: And you're clearly over it.
Chloe: Awkward factor 8. So basically what you're saying is that you're afraid that in the heat of the moment you might...please don't make me finish this sentence, Clark.
Clark: Well, you see, that's the thing. I'm not sure what would happen. I mean if I couldn't control myself...
Chloe: Okay, you know, Clark, right there that's something that can't never be unseen.
Clark: It's not funny.
Chloe: No, you're right, it's not. It's just that this conversation definitely cements me as your Krypto-hag.
Clark: How far do you want to cross the friendship boundary?
Chloe: Since when do we have boundaries?
Lois: What do I know about being a campaign manager?
Jonathan: What do I know about being a state senator?
Lex: (to Lionel) You know, you really don't have to quote The Art of War to me, Dad, I read it cover to cover three times before I finished high school. Although, I still would've preferred a bike for my 14th birthday.
Clark: Lex, why is the Senate seat so important to you?
Lex: It's a stepping stone.
Clark: To what?
Lex: That's like Apollo asking Icarus why he's building wings.
The following scenes were not included in the episode:
1. Samantha makes a phone call to Jonathan, who tells her in turn not to call again. Afterward he takes his pills, prompting Martha to question if the election is worth the strain on his heart.
2. Much to the dismay of Clark, Lois covers Lex's campaign posters with Jonathan's posters.
3. Jonathan receives another call from Samantha and tells her not to call yet again. He also tells her that he won't back out of the campaign and to refrain from threatening his family. After hanging up, he sees a scarecrow (with a picture of his face) being burned.
4. Samantha is shown to be shaving her head.
5. Clark convinces Chloe to trace dial the number of the call, allowing him to use his superhearing to trace the person (Samantha) calling Jonathan.
6. Jonathan thanks Clark for helping him at the rally.
Annie Burgstede says that when casting for the role of Samantha Drake the show's producers were looking for someone willing to shave their head for a one-off episode.
