From the Capitol Hill Cubans blog on today's Castro-visa controversy (hypertext links are mine):
Today, national Republicans criticized the Obama Administration for granting a U.S. visa to Cuban dictator Raul Castro's daughter, Mariela. Democrats have responded by pointing to the Bush Administration, which gave Mariela Castro a visa in 2002.
The fact is that two wrongs don't make a right -- both the Bush and Obama Administrations erred in doing so.
But it's actually worse now. Prior to Raul Castro becoming dictator-in-chief in 2006, few non-Cuba observers even knew that Raul had a daughter (let alone two). Since that time, the Cuban dictatorship has turned Mariela Castro into its most prominent public relations figure.
