From Pensacola to Miami, the Republican primary is in full swing. Newt Gingrich, Mitt Romney and Rick Santorum are blanketing the state with rallies and personal appearances. The airwaves are full of campaign ads.

In Cuba this weekend, President Raul Castro will preside over the first meeting of the island's all-powerful Communist Party since last April. Castro has lowered expectations for any new economic reform announcements, saying that internal party affairs will be the business at hand.

But many Cubans will be watching for signs of who is rising in the party's ranks — and who could take over after Raul and Fidel Castro, both in their 80s, are gone.

Disgraced lobbyist Jack Abramoff has been making the rounds lately. He's out of prison. He has a new book. He's in a talkative mood. So I figured it was a good time to ask him about the business of lobbying — not about what he did that was illegal, but the ordinary, legal stuff.

The firm he worked for was called Greenberg Traurig. I chose a year at random when Abramoff was working there, and picked a client who I hoped would be fairly typical. I chose Tyco International, a multinational corporation that in 2003 gave Abramoff's firm $1.3 million.

With just four full days to go before Tuesday's crucial Florida primary, the four remaining major Republican presidential candidates gather tonight for another debate.

People with sickle cell trait carry one copy of a gene that can lead to an abnormal type of hemoglobin, the oxygen-carrying molecule in red blood cells. (Two copies of the gene lead to sickle cell disease.)
