It took two days for Hillary Rodham Clinton to break her deafening silence on the controversial issue, surrounding her private email address.

Then, at the gala for the Democratic group EMILY's List, she spoke to the crowd, bearing an easy laugh and regal posture, as if she's not at the center of a political turmoil.

For some Democratic activists, the controversies including foreign donations to the Clinton Foundation and the use of her private email address to do official business seemed to be raising concerns about her openness, sincerity and ethics.

 These have led them to look for other options for 2016.  After all, they say, these aren't what they call tabloid scandals but are issues concerning national security and her job as a top diplomat.

For Boyd Brown, a Democratic National Committee member from South Carolina, the flood of allegations against Clinton poses a great danger to her presidential ambitions despite her commanding lead in early polls.

"Nobody down here wants a coronation," Brown said. "We need options. Who knows what could happen. It's always good to have more than one candidate running."

Brown also criticized Clinton and her team's way of handling the burst of negative attention, saying this could be an indication that their mistakes during the 2008 campaign may be resurfacing.

"It almost reminds you of the sense of arrogance that we saw in 2008, that 'we're going to do what we want,'" said Brown.

But as the party makes the survey, no other credible contender emerged.

"The problem is, there's nobody out there who's not Clinton who's the equivalent of Barack Obama," said Larry Drake, chairman of the Portsmouth Democrats in New Hampshire.

While Sen. Elizabeth Warren remained popular within the party, few see her as a strong candidate. Vice President Joe Biden is well-admired among Democrats, but will most likely not succeed in beating Clinton.  Another possible bet is former Maryland Gov. Martin O'Malley, who barely scored in early polls.

The realization for most in the party was that while Clinton isn't an ideal public figure, she remains to be the only realistic bet who could win a presidential election.

Should there be no Democrat to beat Clinton, the Republicans are confident the email scandal alone could weaken her initially strong fight.

Many Republicans said the email saga can sink deep into her campaign as it carries with it an image of Clinton's leadership as one that is deceptive and skirts the rule.

Until all questions are left unanswered, combined with a lack of clear vision as to what constitutes a new Clinton campaign, her journey to the White House remain uncertain.
