Inside Baseball: In what may be part of an organized Republican Party effort to block the steamrolling candidacy of Donald Trump, one time presidential candidate Mitt Romney plans to deliver what’s being described as a “major” speech today on the state of the race for president. Romney’s lieutenants are telling reporters on background that Romney is “going after” Trump.

Republican leaders and moneymen are pouring millions of dollars into anti-Trump television ads in Florida while trying to figure out how they can engineer a contested convention next summer to install a nominee other than Trump.

Florida may be the battleground for the heart, soul, and future of the Republican Party. If Marco Rubio loses his home state he could be out. Ted Cruz might not be able to overcome Trump. Then the fight would be for the Republican establishment to deny Trump the number of delegates he needs to go to the convention as the pre-ordained candidate.

While there’s plenty of politics going on behind the scenes, the Republican fractures are public. House Speaker Paul Ryan criticized Trump for not disavowing support form the Ku Klux Klan. And Trump fired a warning shot at Ryan. “Paul Ryan, I don’t know him well, but I’m sure I’m going to get along great with him,” Trump said on Super Tuesday. “And if I don’t, he’s going to have to pay a big price.”

The Dwindling Crowd: Republican candidate Ben Carson is skipping tonight’s debate in Detroit after saying in a statement, “I do not see a political path forward.” The retired surgeon, for a while, was the only candidate who came close to Donald Trump’s lead, but on his last day in the race Carson’s voter support was at 9 percent to Trump’s 35.6.

Court’s in Session: The four liberal members of the Supreme Court yesterday said that the Texas abortion clinic law that would close down most of the clinics in the state served no medical purpose and is unconstitutional.

That leaves the court split 4-4, at the least, with Justice Anthony Kennedy in the balance looking for more evidence that the law will cause harm to women.

Claiming it’s for the safety of patients, the Texas legislature passed a law requiring clinics to have the facilities of mini-hospitals, and doctors with admitting privileges at local hospitals. Few clinics can meet the standard, making an abortion very difficult to obtain in Texas.

Nation: Aubrey McClendon, the energy executive who powered the oil shale industry, died yesterday in a car accident just a day after he was indicted on federal charges of rigging bids for oil and gas leases. He was 56.

McClendon had been CEO of Chesapeake Energy Corp. Police said his car drove straight into a the wall of a bridge at high speed and burned.

Shelter from the Storm: Singer songwriter Bob Dylan has sold his long-rumored notebooks to be held in an archive for study in Oklahoma. It’s not only notebooks. Dylan scholars thought there were just two or three critical notebooks, but the collection includes 6,000 documents and bits of memorabilia. Dylan was a focused writer and re-writer who scratched out lines and added new ones in notebooks and on coffee-stained hotel stationary. Researchers will be poring over the Dylan archive forever, and probably never unlocking the enigma of the man.
