Despite their lack of success at the national level, third parties have had better luck in ______ races.

Answers

Answer:

Despite their lack of success at the national level, third parties have had better luck in local races.

Explanation:

Third Party is the name of any political party that occupies a minority space within the American electoral system, that is, any party other than the Democrat or the Republican. This category includes parties such as the Green Party or the Libertarian Party, which have never achieved great results at the national level.

Even so, these parties have obtained positive results at the local level. Thus, they have managed to obtain seats in state legislatures, mayors and other lower positions, mainly based on the popularity at the local level of some of their candidates.

Throughout the book and in these final chapters, Krakauer points out several instances where Chris McCandless was in the vicinity of where he was trying to go or was closer to help than he knew. Why might Krakauer dwell on tracing just how close Chris was to being saved or coming out alive?

Answers

Answer:

Krakauer is concluding, from what he knows of McCandless, that he is a sane individual, if not brilliant. However, Krakauer had an experience very similar and can relate to McCandless and his hunger for adventure. He does not think McCandless was batty but as an explorer The narrative works almost as a countdown, starting on July 8, 1992 with McCandless’s return to the bus after finding the Teklanika too flooded, pauses the narrative for a discussion of his physical decline, then enumerating each remaining day at a time. His quotations from McCandless’s diary adds to the poignancy and drama of these last days, as does the inclusion of the detail that McCandless wanted to leave the wild. His diary records that he is now trapped, despite his desire to return, lending the chapter a fatal tone at the same time that Krakauer builds narrative urgency.
