It's a question many Democrats have been asking over the last 24+ hours: how did Hillary Clinton lose to Donald Trump? 

We've already taken a look at why the polls were so wrong and examined the big turnout for Trump among white evangelical voters. 

But Joe Trippi said today that from his analysis of the numbers, this was simply a "relatively low turnout election."

He noted that Clinton came nowhere close to the vote totals for Barack Obama in 2008 and 2012 and barely got more votes than John Kerry in 2004, despite millions more people registering to vote in the last 12 years.

"The vaunted turnout machine just didn't function, it didn't get the vote out," said Trippi, pointing out that Trump's 59.7 million votes are less than what Mitt Romney received. 

Meantime, Clinton received 59.9 million votes (with ballots still being counted), which is about 5 million lower than Obama in 2012 and only about 1 million higher than Kerry.

"I think it's a little bit more [that] the campaign just didn't get out the vote. The votes were there in places like Michigan, Wisconsin and Pennsylvania, they just didn't turn out," said Trippi. 

Ed Rollins, who ran Ronald Reagan's successful 1984 campaign, said Trump did succeed in turning out the GOP base and ran much stronger than Romney did in rural areas.

Rollins said to be a successful president, Trump must continue his positive "sales job" about his ideas directly to the American people.
