Clinton's probably wanting to play it safe, plain and simple.
That just feels like the wrong attitude toward this election. Donald Trump's success partly exists because "playing it safe" is perceived to be what's been happening the past 16 years and what feels like malaise among the general public set in. If there's a time to be bold, it's now.
Hillary received far more votes than Trump did.
1. Trump had far more opponents
2. The Democratic race stayed heated much longer than the Republican race
True, but you're missing the point. You can't make broad generalizations about the "mood of the public" based off the <10% of eligible voters that cast a vote for Trump.
