PROBLEM: HAVANA (Reuters) - With revolutionary leader Fidel Castro dead and his brother Raul vowing to step down as president in 15 months  it will soon be the hour of heir apparent Miguel Diaz-Canel  an advocate for modernizing Cuba's state-run media and abysmal internet access.
 Diaz-Canel  was elevated to the position of first vice-president in 2013  putting  him  next in line for the presidency.
At 56   he  is a relative youngster in the ruling Communist Party's leadership and will need to appeal to younger generations if Cuban communism is to thrive beyond the Castro brothers.
 He  has already established press and internet freedom as signature concerns  a potentially disruptive change in a one-party state that has monopolized the media for nearly 58 years.
Otherwise  however   he  has a much weaker public profile than the Castros and it is not clear what policy changes  he  would push through.
Until now   he  has held to the party line or avoided public comment on key issues such as economic and political reforms or relations with the United States  which were overhauled by Raul Castro and U.S. President Barack Obama over the past two years.
Still  experts say  his  position as heir apparent is solid and that  he  would have to stumble badly for someone else to leapfrog  him  and become the next president in Cuba's arcane system for choosing its leader.
Born after the Castros took power in 1959   Diaz-Canel  is a child of their revolution who rose through the Communist Party by cultivating relationships within the political elite while avoiding the show-boating that ended the careers of other pretenders.
" He  has the advantage of having outlived  his  predecessors (as heir apparent) " Christopher Sabatini  a Cuba expert at Columbia University's School of International and Public Affairs  said on Monday.
 Diaz-Canel  has been careful not to eclipse Raul Castro and is so cautious as to come off as dull and gray   his  public statements largely unmemorable.
" He 's sublimated any ambitions  he  may have had  so the question is what  his  role and power will be among the old guard. Most people try to imagine  him  bridging the new generation and the historic one. That should be challenging " Sabatini said.
That reserved behavior and the government's secretive nature make  Diaz-Canel  largely a mystery to all but Cuba's political elite.
U.S. officials say they know little about  him   and most Cubans outside  his  hometown of Santa Clara know even less.
If  he  does take over in 2018   Diaz-Canel  will be following 59 years of rule by the Castro brothers  one who was gifted with abundant charisma and the other who commanded the absolute respect of top military and political figures.
" He  will be the first civilian president of the revolution and that will require the confidence of the military " said Arturo Lopez Levy  a former political analyst for the Cuban government whose mother taught Diaz-Canel at university.
 Diaz-Canel  chose to pedal.  He  would navigate the provincial capital Santa Clara  vying for space on narrow streets clogged with horse-drawn carts  motorcycle taxis and pedestrians.

PROBLEM: "2017 was a strong year for Facebook  but it was also a hard one " Facebook founder and  CEO Mark Zuckerberg  said in a statement. "In 2018  we're focused on making sure Facebook isn't just fun to use  but also good for people's well-being and for society. We're doing this by encouraging meaningful connections between people rather than passive consumption of content."
 Zuckerberg  noted that the company's recent news feed changes  such as reducing the volume of viral videos  have caused time spent on Facebook to decline by about 50 million hours every day - an average of about 2 minutes per person every day.
On a conference call with investors   Zuckerberg  emphasized that time spent alone offers limited insight into the value of the social network and that  he  expects short-term drops in time on the site to make the product stronger in the long-term.
"By focusing on meaningful interactions  I believe that the time spent on Facebook will be more valuable "  Zuckerberg  said. "If people interact more  it should lead to stronger community. When you care about something  you’re willing to see ads to experience it."
Facebook’s results come just a few weeks after  Zuckerberg  announced that  the company  plans to make a year-long shift across  its  products to prioritize interactions between friends and family and reduce the prominence of unpaid posts by brands and publishers. In the near-term  the change will cause news to make up only 4% of news feed  down from about 5% currently. Facebook plans to display news sources in accordance with how users rank their “trustworthiness.”  Zuckerberg  also said  the company  plans to elevate local news in a push to help “build community.” Facebook correctly warned that the changes could lead to a decrease in time spent on the social network in the short-term. However   Zuckerberg  has said  he  sees the shift as critical to Facebook’s long-term success as a business and product.
When Facebook reported its third quarterly earnings in November   Zuckerberg  said  he  was “dead serious” about addressing the social network’s security and safety issues  ranging from election meddling to moderation issues  such as violent live videos and misinformation.  Zuckerberg  warned that the bolstered efforts “will impact” the company’s profitability.  The company  said last year  it  plans to double  its  headcount working on safety and security from 10 000 people to 20 000 people over the course of 2018  and add thousands more content moderators. (Facebook said it has 25 105 employees as of December 31  up 47% from a year earlier.)
Zuckerberg continues to emphasize video advertising as key to the future of the company’s business. Facebook recently added a “Watch” section for video shows and series  which competes with Google-owned YouTube and is intended in the long-term to foster interaction between friends  family and groups. Higher-quality content in the tab could drive stronger video ad sales over time.  Zuckerberg  also noted in Wednesday's conference call that  he  expects "Stories" -- chains of disappearing photos and videos -- to overtake posts and feeds as the most common content format across apps  and that the growth of the feature will shape how Facebook evolves its apps and business.

PROBLEM: The Senate Republican leadership would like to make  Mitt Romney  the chairman of the National Republican Senatorial Committee (NRSC) if elected to the Senate  according to Republican donor sources.
The Atlantic reported last Friday that according to a Republican donor with direct knowledge of the discussions  the Senate Republican leadership expressed interest in making  Romney  the next leader of the NRSC.  Romney  would replace current chair Sen. Cory Gardner (R-CO).  The NRSC chairman  plays an influential role in fundraising and recruiting future Senate Republican candidates.
On a call last week Gardner revealed to a donor that he and the Senate GOP leadership âliked  Romney â as a potential candidate for the NRSC chairmanship.
The Atlantic reported that two sources close to Rommeny suggested that Senate Majority Leader Mitch Mcconnell told  Romney  that if  he  were to run for the Senate   he  would have more influence than rank-and-file senators.
One source close to  Romney  suggested that McConnell would like to push for  Romney  to become NRSC chair to boost party fundraising.
The  Romney  source  âItâs definitely out there  thereâs no question about that. My guess is McConnellâs pushing  it  because  it  would be good for the party and good for fundraising.â
The former Massachusetts governor and failed presidential candidate is expected to make an announcement on February 15 regarding Utahâs Senate race. Sen. Orrin Hatch (R-UT) announced in January he is retiring and multiple reports suggest  Romney  is eyeing a run.
 Romney  and Trump have had a longtime rivalry over the last couple of years.
âAffirmation of the Paris Agreement is not only about the climate: It is also about America remaining the global leader â  Romney  tweeted last May.
Affirmation of the #ParisAgreement is not only about the climate: It is also about America remaining the global leader. â  Mitt Romney (@MittRomney)  May 31  2017
Reports from Politico last December suggested that President Trump wanted to block  Romney  from running for the Senate.
 Mitt Romney  took to Twitter in January to attack President Donald Trump for allegedly calling Haiti and African countries âshithole countries.â
The poverty of an aspiring immigrantâs nation of origin is as irrelevant as their race. The sentiment attributed to POTUS is inconsistent w/ Americaâs history and antithetical to American values. May our memory of Dr. King buoy our hope for unity  greatness  & âcharity for all.â  â Mitt Romney (@MittRomney)  January 15  2018
President Trump rejected  Romney  to serve as his secretary of state  instead  choosing Rex Tillerson.
Jeb Bush  another former governor and failed presidential governor  backed  Mitt Romney  in a potential bid for the U.S. Senate in 2018.
Bush tweeted on January 15  â Mitt  would make a phenomenal addition to the U.S. Senate. I hope  he  runs.â
