This article from the Washington Post was published in April 2014, however I doubt very much if the correlations have changed. It’s date also shows how long the US has been flirting with the idea of military intervention in Ukraine.
The article, written by political scientists Kyle Dropp (Darmouth), Joshua D. Kertzer (Harvard), and Thomas Zeitzoff (Princeton) is entitled “The Less American’s Know About Ukraine’s Location, The More They Want the U.S. to Intervene.”
The article is well worth reading. Below is the article final paragraph:
However, the further our respondents thought that Ukraine was from its actual location, the more they wanted the U.S. to intervene militarily. Even controlling for a series of demographic characteristics and participants’ general foreign policy attitudes, we found that the less accurate our participants were, the more they wanted the U.S. to use force, the greater the threat they saw Russia as posing to U.S. interests, and the more they thought that using force would advance U.S. national security interests; all of these effects are statistically significant at a 95 percent confidence level. Our results are clear, but also somewhat disconcerting: The less people know about where Ukraine is located on a map, the more they want the U.S. to intervene militarily.
