As Lisa walks through the school’s playground, she sings Three Dog Night’s “One is the Loneliest Number” in this episode of The Simpsons.

The playground melts away due to the rain, and indoors, Lisa wanders the hallways before a spit wad hits her. Looking at the bright side, Lisa feels like at least she gets attention. She then realizes that Bart is the one who is aiming at her.

Lisa escapes to the school library and wards Bart away with a copy of Little Women. There, she meets a new student and learns her name to be Isabel (guest voice Eva Longoria) by deciphering an anagram.

When Isabel calls the house asking for Lisa, Homer picks up the phone. Lisa gets excited over this new friendship. Homer asks Bart why he doesn’t get new friends.

Almost on cue, Milhouse walks in talking about finding a green M&M in his inner ear. Milhouse hold on to the M&M as Homer ponders whether he should eat it or not, but Santa’s Little Helper gets to it first. Now, Homer wonders whether he should eat it even though it has been in Milhouse’s ear and the dog’s mouth.

Before Homer makes a decision, Marge wedges the M&M back in Milhouse’s ear.

Isabel and Lisa agree to do a presentation on Franklin Roosevelt together. However, the presentation doesn’t really go as planned when Lisa discovers that her new friend is a Republican, and not the first George Bush kind.

Lisa expresses her concern, and Marge tells her daughter that it’s just a phase. Case in point? Marge used to help out with campaigning for the Republican Party, but look at her now.

Over at the school library, Lisa bumps into Isabel. Both girls reconcile, despite Isabel also hearing the same advice from her own mother, stating that Lisa’s just going through a liberal phase.

The girls hug it out, but guess who’s spying on them?

The Springfield Republican Party take notice of this and attempt to infiltrate the upcoming school election in which Lisa is running against Isabel…and Ralph.

When Isabel opens her school locker, she finds Mr. Burns stuffed inside. Over a sundae, Isabel converses with the Republican Party, who believe that Isabel is its future.

In the end, will this be a friendly competition between two peers, or will this cost Lisa her one and only friend?
