ELI5: Why is the Asian vote not fought for during Presidential campaigns?

As the Presidential election gets closer, we constantly hear about the nominees fighting for the Hispanic/Latino and Black votes since they can affect the outcome of the election. One thing that I hardly ever hear, if ever, is fighting for the Asian vote. As a minority group, the Asian community represents 5.6% of the population or roughly 17,999,453 people according to the US Census conducted in 2015. To put it in perspective, Hispanics/Latinos made up 17.6% (56,569,712 people) and Blacks made up 13.3% (42,748,703 people).

In an election where every vote counts, Presidential should be seeking to acquire votes from all groups. With a nearly 18 million people, the Asian community is a still a considerable amount of potential votes that could affect outcomes in certain states. So why is it that they hardly get mentioned at all?
