Political veterans, including former Florida Governor Jeb Bush, former Hewlett-Packard CEO Carly Fiorina, Ohio Governor John Kasich, former Arkansas Governor Mike Huckabee, Texas Senator Ted Cruz, Florida Senator Marco Rubio and New Jersey Governor Chris Christie, will try to shift the focus of the campaign on the economy and foreign policy when the third GOP presidential debate happens on Wednesday, October 28 at the Coors Events Center at the University of Colorado in Boulder.

The event, dubbed Your Money, Your Vote, will be hosted by CNBC, will start at 8 p.m. Eastern Time.

As the campaign for the Republican presidential nomination heats up, season politicians find themselves trailing to real estate developer and reality TV star Donald Trump and soft-spoken surgeon Ben Carson, who have played on provocative rhetoric and controversial stance on immigration policies, and others.

Ironically, these seasoned politicians are being trampled by Trump and  Carson, who are getting a firm hold in the polls as a possible candidate of the Republican Party in next year's presidential elections, said Reuters.

With Trump and Carson holding a firm grip on the race in polls of likely Republican voters for the November 2016 election, the forum comes at an increasingly perilous time for lower-ranking candidates.

"If they run this thing well and push people to see if they're smart on the economy and job creation and how fiscal restraint fits into that, you could finally start separating the sheep from the goats on an important issue," an official in the campaign of one of the Republicans vying against Trump told Reuters.

Things to Watch For at The Third Republican Presidential Debate

Seth Masket, an associate professor of Political Science at the University of Denver said that with the venue of the debate set in Colorado, that says a lot that the Republicans consider the state as a crucial one.  And  they will be trying to contest it," Masket told TJC Newspaper.

"We're at this point in the process where things are going to start to shake out", Masket said. ProgressNow Colorado is calling for at least half of the seats to be made available for students, and while it doesn't say it outright, its recent press release seems to accuse the Republican candidates of being scared of the progressive student body. It's also 25 percent higher than what CNN got during its Republican debate in September (when Donald Trump challenged CNN chief Jeff Zucker to donate the network's ad revenue to veterans charities).

The debate will be divided into two parts. The candidates with an average of three percent in this specified group of national polls will take the stage shortly after 8 p.m. ET for a two-hour debate. The candidates who met the minimum threshold of one percent in any one of the specified group of national polls will take the stage at 6 p.m. ET.

The following 10 candidates will take the stage shortly after 8 PM ET:

    Donald Trump: 25.22

    Ben Carson: 19.78

    Marco Rubio: 9.67

    Jeb Bush: 8.11

    Carly Fiorina: 8.11

    Ted Cruz: 6.89

    Mike Huckabee: 3.56

    Chris Christie: 3.00

    John Kasich: 3.00

    Rand Paul: 3.00

CNBC took into consideration at least nine "methodically sound" released between September 20 and October 20 and gave priority spot to candidates with an average of at least three percent. Four candidates who received less than 1 percent of the polls will participate in the 6 p.m. debate.
