The first of three presidential debates is Wednesday, and both candidates are preparing their arguments and are prepping voters prior to their showdown.

The debate is taking place at the University of Denver, and will be hosted by Jim Lehrer, the host of NewsHour on PBS, and will only focus on domestic policy. There are likely three main hot-button issues the candidates will talk about.

But, they will likely only talk about actual issues after Mitt Romney tries to compensate for his “47 percent” gaffe. This is an attempt to cover some quick ground on President Barack Obama, who is beating Romney by two percent in the latest polls, but both Romney and Obama will likely start off with their health care plans.

Many politicians called Romney’s health care plan that he implemented while he was governor of Massachusetts “Obamney Care,” because of the striking similarities between the two plans.

However, Romney maintains that his plan was ideal for a state and is not a national solution.

Romney is a supporter of universal healthcare, which is similar to “Obamacare,” however, he wants to delegate its implementation to the state level, rather than the national level.

Romney has previously said that he would keep coverage for Americans with pre-existing conditions, and would keep the stipulation that adult children can stay on their parents’ health care plan until they are 26 years old.

During the debate, look for Romney to go after Obama for the individual mandate section of his plan, which requires all Americans to have health care, something that Republicans dislike about the bill.

Something that will definitely come up is the budget and National deficit, especially because the deficit under Obama is something that is always referenced in Romney campaign ads.

Romney’s main position on the budget is similar to Reaganomics, in which tax cuts are given to the wealthy, specifically people who have incomes less than $200,000 a year, and people aged 65 years or older.

Obama is upholding his original stance that he took during his campaign in 2008, a message of developing renewable energy and creating more jobs to benefit the American economy and cut down on the deficit.

Third, and most likely tied into the budget, will be the two candidates’ economic policies.

Romney became the second Republican presidential candidate to release a full economic plan Sept. 6, which Romney called “Day One, Job One.” The plan’s main objective is for Romney to initiate 10 major actions on the first day of his presidency, five bills and five executive orders.

Among the bills is one that would reduce the corporate income tax rate to 25 percent, one that would start free trade with Colombia, Panama and South Korea and one that would cut non-security discretionary spending by $20 billion.

Obama’s economic plan mainly relies on repealing the tax cuts that former President George W. Bush put in place, and bringing the federal tax rates back to 40 percent, similar to the level during President Bill Clinton’s administration.

While those are some of the main points the candidates will likely touch on, also look out for debates concerning same-sex marriage, which Obama expressed his support of a few months ago, as well as stem cell research and the decriminalization of marijuana. Not all of those things may be talked about, but they would certainly make for an interesting debate.
