PROBLEM: The leader of India's main opposition Congress party   Sonia Gandhi   has retired from  her  post  the party confirmed on Thursday.
 Her  son   Rahul Gandhi   has been elected unopposed as the new president and will officially take charge on Saturday.
 Mrs Gandhi   71  has been the party president since 1998.  She  was elected to parliament in 1999.
 She  is  however  not retiring from politics and will continue as a member of parliament  the party said.
 Mrs Gandhi  entered politics in 1994   three years after after  her  husband  former Prime Minister Rajiv Gandhi  was assassinated.
 Her  power derived from being the head of the Nehru-Gandhi dynasty  which has led the Congress party and has ruled India for most of the years since it became an independent nation in 1947.
After distancing  herself  from politics following  her  husband's death   Mrs Gandhi  was initially seen as a reluctant and almost reclusive politician.
Under  her  leadership  the party turned in its second-worst performance since independence in the 1999 elections  but won the general elections in 2004 and 2009.

Mrs Gandhi  an Italian-born Catholic  would have been the first foreigner to become Indian prime minister had  she  not surprised everyone by turning down the post after  her  general election success in 2004. Yet  many considered  her  the de facto head of the Congress government.
In recent years  Mrs Gandhi  has faced health issues. In 2011   she  had surgery in the US for an undisclosed medical condition and in 2013  she  was taken to hospital from parliament after falling ill.

SOLUTION: Sonia Gandhi

PROBLEM: The good news for Indy is that the only coaching vacancy still looks pretty attractive â if  Andrew Luck  is healthy.
 Luck   meanwhile  continues to be the big question as  he  rehabs from last January's surgery for a partially torn labrum in  his  throwing shoulder.
Some believe McDaniels' sudden change of heart was related to doubts about  Luck 's health.
On Wednesday  though  he attempted to alleviate lingering concerns about  Luck  while acknowledging the franchise quarterback still hasn't thrown a football since returning from Europe late last year.
"At this point  we feel very strongly that  Andrew  is in a good place.  He  doesn't need surgery " Ballard said. "I have not gotten that from the two doctors that  he 's seen here after the season.  His  strength is good.  He 's working on  his  throwing motion and  he 's working on  his  arm speed right now.  He  has not picked up a football  but  he  is throwing balls  working on arm speed.
" He 's going to do everything right to get  himself  ready to play and I'm very confident   he 's very confident  that  he 's going to come back and prove a lot of people wrong " Ballard added.

SOLUTION: Andrew Luck

PROBLEM: But on important issues -- from opposing new settlement building in the Occupied Territories , to supporting the nuclear framework with Iran -- Clinton has not taken the hawkish side , as so many of her liberal critics fear she would do if she becomes president . 
None of this is to suggest that Clinton will be Robin to Obama 's Batman . 
Then there are the issues of wage stagnation and income inequality , two longstanding trends that will likely be at the heart of Clinton 's pitch to voters . 
A recent report drafted by Clinton allies , including Neera Tanden and former Treasury Secretary Lawrence Summers , laid out what David Leonhardt at The New York Times described as the "first draft" of a Clinton economic platform : a mix of improving education , providing direct aid to the lower and middle classes , bolstering child care , strengthening financial regulation , raising taxes on the wealthy , and cutting taxes on the middle class . 
Then there are three issues -- gay marriage , women 's rights , and immigration reform -- that are of immense ideological and electoral importance to the Democratic Party , and can expect an ardent champion in Clinton . 
It depends on whether you see Obama 's foreign policy , which is so entwined with Clinton 's tenure at the State Department , as a disaster for which the U.S. is primarily responsible or the result of organic crises erupting in the Middle East and elsewhere that are largely beyond the administration 's control . 
The fear is that a President Clinton , likely facing a Republican-controlled Congress , will not be content to be the safeguard of Obama 's legacy ; that she will foolishly trade away Democratic priorities like entitlements in some ill-conceived Grand Bargain ; that she will succumb to the many demons whispering in her ear , whether they be Wall Street bankers , neoliberal triangulators , purveyors of hoary Beltway wisdom , or the Wormtongue-like advisers that are always hovering around Clintonland . 
But if Clinton is smart , and I believe she is , she will realize that the days of repealing Glass-Steagall are over , and that her ticket to a historical legacy is to be part of a great era of policy reorientation away from the conservative-neoliberal consensus that has produced decades of middle-class stagnation and one huge financial crisis . 
In contrast , Hillary Clinton , who officially announced her campaign for president on Sunday , will not face the same array of challenges should she be elected -- which is another way of saying that she will have fewer opportunities to remake the political landscape in her image . 
To that end , there are ways Clinton could be a far more effective president than Obama . 
But there is still plenty for Clinton and the Democratic Party to do -- and plenty of space to leave her mark . 
She is also better at greasing her own side with the kind of glad-handing and thank-you-card-writing that Obama constitutionally dislikes -- my guess is that another President Clinton would have an easier time getting her side to fall in line on , say , the Iran deal than President Obama . 
First , simply by virtue of being elected , Clinton could consolidate the gains that Democrats have made in the Obama era . 
At the very least , Clinton would face pressure from her party and her base to protect those reforms . 
Many critics have accused Clinton of helping turn Libya into a failed state , and note that her support for U.S. intervention echoed her support for the Iraq War . 
It is worth remembering that in 2008 , Clinton actually ran to Obama 's left on the issue , which should give progressives hope that policies like the public option and greater subsidies will be on Clinton 's 2016 agenda .

SOLUTION:
Hillary Clinton
