Answer: The contrast and contradiction in "Why We're Running for Office" are that the teens who are postulating for senate, said that they will not stop being normal teenagers.
Explanation: In "Why Were Running for Office" It is stated that a group of teenagers will postulate for senate in the real elections. Throughout the article, it is described how powerful and serious their proposals are, however; at the end of the article, the teenagers claim that they will not stop doing teenage activities, such as hanging out with friends, etc. The reader doesn't expect that contrast and contradiction since they are being serious about their campaign, just like adults do.
