Who isn't visiting Colorado this week?

John McCain's daughter Meghan will sign copies of the children's book she wrote about her father in Highlands Ranch today. Then the Republican presidential candidate will arrive later in the day in order to attend rallies in Denver and Durango on Friday.

Hillary Clinton will also be making her first trip to Colorado to campaign for Barack Obama. She'll attend a rally in Aurora on Friday.

Obama will be here himself on Sunday but no details have been released yet. It will be one of his first appearances back on the campaign trail after a break to be with his ill grandmother in Hawaii.

This week, Colorado also had visits from Joe Biden, Sarah Palin, Palin's husband Todd and independent candidate Ralph Nader.
