(NBC) -- President Obama and Mitt Romney are getting ready for their first debate.
The president will be behind closed doors in Nevada for the next two days, preparing to face Romney in Denver Wednesday.
"He's a good debater. I'm just okay. But what I'm most concerned about is having a serious discussion about what we need to do to keep the country growing," Mr. Obama told supporters over the weekend.
Both sides are downplaying expectations.
A senior aide to the president says Romney will be "prepared, disciplined, aggressive."
Romney's debate partner calls the president "a tough debater".
"Barack Obama is going to be formidable. I think it'll be a good debate, but I certainly would not underestimate what Barack Obama brings to it," Senator Rob Portman said.
In today's Wall Street Journal Romney calls President Obama's foreign policy "dangerous."
Romney's debate plan: Clearly and concisely explain how he can fix the economy.
"I expect to be able to describe that in a way people will understand, and if they do, I'll get elected," Romney predicts.
Both sides are already planning their post-debate rallies.
