PHILADELPHIA - There have been plenty of attacks and name-calling from all sides of the political spectrum throughout the presidential primaries and Democratic and Republican conventions, but what else can be expected between now and Election Day?

Following the close of the Democratic National Convention Thursday, the battle for the White House now officially enters a new phase: the general election. And that means a marquee matchup between a pair of candidates who have exceedingly different styles.

Republican Donald Trump dominated a field of nearly 20 GOP rivals by successfully branding his opponents. The billionaire businessman said that Jeb Bush was "low-energy," mocked "Little Marco" Rubio and, of course, branded the junior Texas senator "Lyin' Ted" Cruz. The nicknames, while unorthodox, stuck with voters. So how does Democratic nominee Hillary Clinton avoid becoming synonymous with another famous Trump nickname, "Crooked Hillary?"

Nassau County Democratic Party Chairman Jay Jacobs is a Clinton friend and prolific campaign fundraiser. To him, Clinton's path to victory is showing voters that she is everything Trump is not.

"She can't stoop to his level," Jacobs says. "She has to show that she has the ideas, that she has the experience, the specifics and the composure and demeanor to be the president and commander in chief."

Hofstra University political analyst Larry Levy says Clinton must stay above the fray if she is going to defeat Trump.

"The way that Trump wins is holding together white, working-class voters in greater numbers than say, Mitt Romney did, and depressing Democratic turnout," says Levy. "And the best way to do that is by getting them to see this as a choice between two impossible alternatives."

That basically means Clinton will have to take off the gloves without getting into an all-out brawl. New York state Comptroller Thomas DiNapoli says he believes she will be successful, but also points out that in this election cycle, it appears that anything goes.

Nicknames aside, one of the two candidates will earn a new title come November, president-elect.
