Answer:
the presidential candidates travel East to <em>West</em>
<em>"</em>west" at the end of the above phrase should be capitalized.
Explanation:
At least, using the capitals or lowercase must be consistent (use both either capital or lowercase).
The correct way is to use capitalization of directions (east, west, north, south) when they represent specific regions. For example, He's is from the South (meaning he is from southern states).
If a direction does not represent any specific region, it should be used lowercase. For example. The south wall of the house is damaged.
As, <em>East and West</em> in the given sentence represent specific regions of the United States, they should both be capitalized.
