Naturally, the thing that is garnering the most attention is the exchange with Senator Coburn wherein he used the phrase "Lucy, you got some 'splaining to do'. A lot of asinine attention will be paid by the armies of the politically correct. Those of us of a certain age just find it amusing since Ricky Ricardo said that so often on "I Love Lucy" with varying (and usually justified) degrees of frustration.
Ethnically, Cubans (which Ricky Ricardo was) are wholly different from natives of Puerto Rico. They combine African and other cultural elements in their ancestry. Judge Sotomayor is of Puerto Rican descent which is much more purely Hispanic in nature. Nevertheless, I will expect to hear nonsense from the humorless Left about this innocent exchange.
President Obama could have done worse in nominating this woman to the Supreme Court. At least Judge Sotomayor has a more compelling claim to American citizenship than does the President! She may be a biased loon, but she comes across very well.
