President Obama will play explainer-in-chief on Thursday, looking to convince Americans that Obamacare is a good deal, just days ahead of open enrollment for a health law that many still find confusing.

Obama will travel to nearby Prince George's Community College in Largo, Md., to make his latest healthcare sales pitch.

"In his remarks, the president will cut through all the noise coming out of Washington and speak directly, in plain and honest terms, about what the Affordable Care Act means for consumers," a White House official said, previewing Obama's remarks.

"He’ll walk through the benefits that have already strengthened insurance protections for the 85 percent of Americans who already have health insurance coverage today, and he will explain what new benefits lie ahead for those Americans who don’t have insurance today," the official added.

Many Americans, however, have still not warmed to the law.

A new Bloomberg poll released late Wednesday found that 60 percent of respondents believe Obamacare will increase medical-care costs. One in three Americans said they would be worse off than they were before the law was implemented.

The White House has long argued that the public will embrace Obamacare once they fully understand its benefits, but that has yet to come to fruition.

The president will trumpet a new Department of Health and Human Services report showing that premiums would be lower than critics predicted. But the analysis also omits a number of data points that would give a fuller portrait of the costs of Obamacare.

Obama's speech also comes in the wake of a 21-hour speech by Sen. Ted Cruz, R-Texas, from the Senate floor against the new health law. Republicans have launched their own campaign to undermine public confidence in the president's signature legislative achievement, saying the "train wreck" comes with a series of unintended consequences that will devastate consumers.

Obama will argue that such GOP rhetoric is empty and ignores a broken healthcare system.

"[Obama] will explain how and when consumers can sign up for insurance – from October 1 through March of 2014," the White House official said, "and will detail the protections that are guaranteed forever under all of the health plans purchased through the marketplace, regardless of which plan is chosen."
