I think so. The bigger question is what will happen with the Asian and Hispanic turnout in the near and midterm future. Will it remain as abysmally low as where it is today or will it slowly start to increase and at least cut the gap somewhat to the much higher black and white turnout? Hispanics have so much to gain from a higher turnout (immigration reform, fear of deportation for family and friends, higher minimum wage, social security, health care, education and a more human foreign policy main among these) and Asians are on average easily the best educated and highest earners of any demographic group, so I think these two factors will help both groups with increasing its turnouts over the span of the next 10-20-30 years. It will be a somewhat slow, yet inevitable process, I think.
Asian Turnout was like 3% of the electorate in 2012 I think and they make up 5% of the US Population. That's not low turnout for an ethnic group in terms of what % they make up of the US Population.
Hispanic turnout you have might have a point but some Hispanics are too young to vote or they are here illegally.
