After Josh is hailed as the "101st Senator" in a newspaper profile, he butts heads with a conservative Idaho Democratic Senator who withholds out his approval of a backlog of military promotions to secure an expensive but faulty missile launcher to be built in his home state. In the back corridors, Will gets a flattering offer from the newly approved Vice President while CJ runs afoul of Leo's temper when she does not stick to the adminstartion's scripted line on an EPA report on coal-based energy. Likewise, Amy earns the President's wrath when she pushes for funding of the First Lady's agenda on violence prevention while Toby pieces together a message calendar to stay on point during Bartlet's second term. 
After Josh is hailed as the "101st Senator" in a newspaper profile, he clashes with conservative Senator Carrick, a Democrat from Idaho. Carrick withholds his approval of a backlog of military promotions so he can secure an expensive but faulty missile launcher to be built in his home state. When Josh pushes Carrick too hard, the Senator defects to the Republican party.
Will gets a flattering offer from the new Vice President, Robert Russell, who wants him to be his Chief of Staff. Will eventually decides to accept, which enrages Toby, as it throws out Toby's plan to move up to a position as a senior policy advisor to the President. He sees Russell as being unworthy and sees Will's move as a betrayal.
C.J. runs afoul of Leo's temper when she deviates from the administration's scripted line regarding an Environmental Protection Agency report on coal-based energy.
Likewise, Amy earns the President's wrath when she aggressively pushes for funding of the first lady's agenda on violence prevention, leading the President to comment that she doesn't need to be there at all.
It turns out the story about Josh's prowess was leaked by Amy as a birthday present. But Josh thinks it is against the "code" of working in the West Wing for him to have better press than the President.
Vice President Russell: I like loyalty, Will. I respect loyalty. But you can run out the clock on a Bartlet Presidency that in effect is over. You can finish something that you never started in the first place. Or you can shape the next presidency from the ground up. Total access. Coach of the team.
