Massachusetts Gov. Deval Patrick (D) said in an interview broadcast Sunday that he's concerned that the notion that Hillary Rodham Clinton is the inevitable Democratic nominee for president in 2016 could turn some voters off.

"She is an enormously capable candidate and leader, but I do worry about the inevitability because I think it's off-putting to the average voter. And I think that was an element of her campaign the last time. As an enthusiastic Democrat, I just hope that the people around her pay attention to that this time around," Patrick said of the former secretary of state on CNN's "State of the Union."

Clinton has not said whether she will run for president in 2016, but she is widely regarded as the overwhelming front-runner for the Democratic nomination if she jumps into the race.

"She's got the capacity. But like any front-runner, she has to be cautious and wise in how she proceeds forward," said California Gov. Jerry Brown (D) of Clinton on ABC News's "This Week with George Stephanopoulos."

Patrick said he has no interest in running for president in 2016.

"This is not the time that's right for me," he said.

He added that while he will support the Democratic nominee for president, he is not playing favorites right now.
