CENTENNIAL, Colo. -- You know Colorado is a battleground state in this year's election when both presidential and vice presidential candidates for the two major parties will be in the state on the same day.

Republican vice presidential nominee Gov. Sarah Palin will be holding a rally in Golden on Monday, the same day Sen. Barack Obama will be in Pueblo and Grand Junction. Obama has also scheduled an event in Denver on Tuesday.

Tickets For Pancake Breakfast Go Like Hotcakes

The McCain-Palin Campaign office released tickets for the "pancake breakfast," Friday but due to the overwhelming demand, the campaign ran out of tickets within eight hours.

In order to accommodate the demand, the campaign also decided to change the event from a pancake breakfast to a morning rally. The event will still be held at the Jefferson County Fairgrounds, but the venue has moved to the Westernaires Arena.

"Coloradans are excited about the McCain-Palin ticket," said McCain spokesman Tom Kise said Friday afternoon. "Our phones have been ringing off the hook and the line has been out the door and into the street. Unfortunately the campaign has no more tickets to give away."

The event begins at 9 a.m., but doors open at 7 a.m. The event is outside, so organizers said people should dress accordingly.

It is the Alaska governor's second visit to Colorado in just over a week.
