It seems the Diaz Balart brothers may be about to lose their "birthright" in the Cuban community in South Florida. Democrats had also hoped to upend Rep. Ileana Ros-Lehtinen, so that poll [all three polls are below] is good news for the GOP.

Yet, in the overall picture, the fact that they are likely to lose one of these seats, and may lose two of three, tells me that what we have been hearing about younger Cubans' willingness to break with the older generation's stalwart Republicanism has some truth to it.

Here are the numbers:

FL-25:
Joe Garcia (D): 39
Mario Diaz-Balart (R-inc): 44

FL-21:
Raul Martinez (D): 37
Lincoln Diaz-Balart (R-inc): 41

FL-18:
Annette Taddeo (D): 31
Ileana Ros-Lehtinen (R-inc): 58
