Bernie Sanders' upset victory Tuesday in the Indiana primary shows Democrats are not quite ready to name Hillary Clinton the nominee.
Every time the race seems headed to the finish, voters decide to extend it, as they did in Michigan in March, NBC News reported. Sanders' win does nothing to knock Clinton off her glidepath to the nomination, since the few delegates he picks will barely dent her massive 300-plus pledged delegate lead.
But it will be a much-needed fundraising and momentum boost to a fading candidate who has pledged to stay in the race until the Democratic National Convention in July, even though his only path to victory involves improbable landslides and fanciful schemes to flip superdelegates.

Clinton's campaign and nervous Democratic leaders may now reassess their indifferent attitude to Sanders. They had hoped for a head start on Trump, but the Republican will instead have the drop on them and Clinton will face incoming attacks on both sides.
