Robert McCallister

Robert McCallister first met Kitty Walker when she interviewed him on her talk show. A recent divorcee with two young children, he was involved in a scandal regarding allegations of infidelity. Kitty was more interested in asking for his help to get her brother Justin out of being sent to Iraq, but Robert could do nothing. With Kitty's talk show folded, Robert asked her to become the communications director for his Presidential campaign. They soon began a romantic relationship, over the vehement objections of her gay brother Kevin, who objected to Robert's record on gay marriage. Thanks to Kitty, Kevin had a brief relationship with Robert's gay brother Jason, which ended badly, not doing much to endear Robert or Kevin to each other, but they came to an understanding.

Robert and Kitty got engaged and had their party at Kitty's family home. Robert's own family, however, stole the spotlight. Robert came under the spotlight when the Republican primary for President kicked into a higher gear. During the Gulf War, Robert was hailed as a hero for something he did not actually do. This secret was revealed during the primary, causing his opponent to question his patriotism. Robert was forced to hire a very skilled consultant named Isaac (Danny Glover), whom he disliked due to Isaac outing Jason while working for one of Robert's primary opponents during a state senate campaign. When Jason found out Isaac had been the one responsible, and was now working for Robert, he was furious, but soon forgave his brother.

Kitty discovered she was pregnant. She had a miscarriage, but wanted to try again. This led to some tension with Robert, who didn't want anymore kids, even though he'd told her otherwise. They worked out the conflict and got married.

Robert soldiered on in his primary campaign, but eventually conceded defeat to the frontrunner, a deep conservative who had engaged in what Robert and Kitty saw as dirty tricks. He asked Robert to be his running mate, much to Kitty's disgust. Robert considered the idea, but ultimately rejected him. In a later episode, Kitty is watching a newscast about the inauguration of Barack Obama, signalling that the show takes place in real time with the actual winner of the race, despite the fictional candidates in this show.
