This sculpture is just another metaphor of those who build their houses on sand - as taught by Jesus in the Bible.
7 “Ask, and it will be given you; search, and you will find; knock, and the door will be opened for you. 8 For everyone who asks receives, and everyone who searches finds, and for everyone who knocks, the door will be opened…. 24 Everyone then who hears these words of mine and acts on them will be like a wise man who built his house on rock. 25 The rain fell, the floods came, and the winds blew and beat on that house, but it did not fall, because it had been founded on rock. 26 And everyone who hears these words of mine and does not act on them will be like a foolish man who built his house on sand. 27 The rain fell, and the floods came, and the winds blew and beat against that house, and it fell — and great was its fall!” 28 Now when Jesus had finished saying these things, the crowds were astounded at his teaching, 29 for he taught them as one having authority, and not as their scribes.
I do not disagree. Since everything about Obama has to do with his ethnicity, this sand image looks wash out. It is fat, and white.
