<p>&#8220;I would have loved to have had the opportunity. I think it is possible [that he could have won].</p> Bernie Sanders says he could have done better then Hillary Clinton 
<p>&#8220;Hindsight is 20/20. I don&#8217;t know.&#8221;</p>

<p>Speaking to NPR Mr Sanders said: &#8220;I think it&#8217;s time for a fundamental reassessment and I think what that reassessment has got to entail is to understand that we cannot have a party that will win if we continue to become dependent on big money interests and campaign fundraisers all over this country.&#8221;</p> 
<p>Discussing the shift of voters from Barack Obama to <a type="internal">Donald Trump</a> , Mr Sanders added: &#8220;I think a lot of people who voted for Barack Obama in 2008, voted for Barack Obama in 2012, and who like Barack Obama, said &#8216;You know what, I am going to go for Trump because he has been clear about feeling the pain of working families.&#8221;</p> 
<p>Speaking to donors in a conference call following her defeat, Mrs Clinton said FBI Director James Comey had played a crucial role in her defeat.</p>
