As I write this post, Rep. Lincoln Diaz-Balart is announcing that he will not run for re-election in Florida's 21st Congressional District. His speech was given this afternoon at Florida International University inside the Law Library, part of which is dedicated to his grandfather Rafael Diaz-Balart.
[Correction] The announcement was broadcast live in its entirety by local news reports. [Full video available here.]
The Miami Herald reports on the possibilities for Rep. Diaz-Balart, and his brother Rep. Mario Diaz-Balart.
[Update: Full speech by Rep. Lincoln Diaz-Balart, and the official announcement by Rep. Mario Diaz-Balart to run for the 21st District. And, questions by reporters after announcement.]
