Respuesta :
The events that resulted in voter frustration in two major political parties were Roosevelt's campaign for the Bull Moose Party.
- The bull moose party is known as the progressive party and is the third-largest party formed in 1912. President T. Roosevelt stood to win the presidency in his own ways. But he did not realize that he had agreed to the conservative republicans of congress and need their support to win the election.
- Republicans were against president Taft and this lead to a slip within the supporter. So he formed a new party named the Bull Moose party as it was a platform for new nationalism.
Thus the events that lead to the voter frustration were the split within viewpoints and political agenda. Hence option B is correct.
