Obama reinforces Hillary Clinton's argument in the Democratic contest

President Barack Obama gave a boost to Clinton's argument that an experienced candidate is required to succeed him in the White House, while rejected comparisons between his campaign in 2008 and Bernie Sanders.

A week before the Iowa caucuses launch the process of choosing the Democratic candidate, Hillary Clinton works to approximate its President campaign and attract more support from their supporters. She has said Sanders preaches laudable goals, but some of them are unreachable. Also argues that it does not have the experience to handle a range of topics.

"One thing that everybody understands is that this work well here you can not afford to focus only on one thing," Obama said in an interview with Politico.

Obama, who remains popular in his party, has said it will not support any candidate in the primary, but admitted that closely observes to see who will succeed him. The kind words about Hillary Clinton can be a powerful discussion topic for your former secretary of state.

All three Democrats in the race for the nomination, Hillary, Sanders and former Maryland Governor Martin O'Malley will have a chance in prime time to present their closing arguments on Monday night, in a nationally broadcast debate by CNN.

Candidates will appear individually on stage, answering questions from moderators and trying to convince voters before voting February 1 in Iowa.

Obama also objected to comparisons between him and Sanders, who is described as the dark horse candidate who excites young voters and has attracted larger audiences. As Sanders gaining ground, analysts began making emphatic comparisons with Obama, who overtook Hillary Clinton and won the nomination in 2008.

"I do not think that's true," the president said when asked about the comparisons.

The Clinton campaign will certainly be happy with Obama's praise.

"She is extraordinarily knowledgeable - and, you know, very intelligent and knows every policy inside and out-and sometimes this can make it more cautious, and more prose than poetry campaign," Obama said about the candidate .
