What conclusion can you draw about Barack Obama helping Hillary Clinton run for president?

Explanation:

It wasn't enough. With some groups he was an asset. With other groups, he was a liability.

It is hard to make a general statement. The reason she didn't get in is that she didn't carry enough of the electoral college seats as she needed to. She won the popular vote by something like 3 million votes, but where she won, the electoral college didn't have enough seats to get her elected. Lately the democrats have had a problem with winning the states that were swing states and could go either way.  Their support is overwhelming in some places but not spread out enough to matter.

The problem was not with Obama. The problem was with the electoral college.

i am not 100% positive but i think it is is b. both are non-partisan jobs

i am pretty sure that members of congress have term limits, can be impeached, and are nominated through direct popular vote.
