Former Denver Mayor and Barack Obama national co-chair Federico Peña will be Colorado's 15th and final superdelegate to the Democratic National Convention after current Denver Mayor John Hickenlooper dropped out of the race Wednesday.

Peña and Hickenlooper were set to face off for the superdelegate position this weekend at the state Democratic convention in Colorado Springs.

But Colorado Democratic Party Chair Pat Waak said Hickenlooper left a phone message with her stating that he had decided to drop out of the race after talking with Peña.

If Peña is confirmed as a superdelegate this weekend, he would be the sixth Colorado superdelegate to endorse Obama.

U.S. Sen. Barack ObamaFormer Colorado governor and Democratic National Convention superdelegate Roy Romer endorsed Barack Obama for president Tuesday, ABC News is reporting.

Romer is the fifth Colorado superdelegate to back Obama; four Colorado superdelegates have backed Hillary Clinton, while five remain uncommitted.

In his announcement, Romer urged other superdelegates to back Obama because "it's important" for Clinton "to know where we are so she is not misled," according to ABC News.

U.S. Rep. Diana DeGetteU.S. Rep. Diana DeGette (D-Denver) won Saturday's CD-1 Democratic assembly unopposed, and suggested her superdelegate vote may go to Barack Obama following the last Democratic presidential primary, ColoradoPols is reporting.

DeGette, who as a sitting Democratic member of Congress is a presidential superdelegate, pledged her support to Hillary Clinton last November. But in her CD-2 Democratic assembly acceptance speech Saturday, ColoradoPols reported that DeGette "said that she would not join in any super delegate cabal to overturn the will of the people as expressed by the popular and pledged delegate count."
