We wrote recently about the chances of putting more presidential faces on Mount Rushmore National Memorial (very slim). Now Barack Obama has weighed in on the issue. Well, sort of.

The likely Democratic candidate for president took a break Friday night between campaign stops in Montana and South Dakota – where the last presidential primaries are taking place on Tuesday – to visit the Shrine of Democracy.

According to a Reuters story, Omaba laughed when asked if he could image his own likeness chiseled into the granite monument someday.

“I don’t think my ears would fit,” he said. “There’s only so much rock up there.”

Obama did a campaign rally in Rapid City Saturday morning, followed by shopping at Prairie Edge in downtown Rapid City and a drop-in at Firehouse Brewing next door.

The Black Hills have taken a rare turn in the political limelight of late. With the Democratic race still undecided, South Dakota has become a focal point for the Hillary Clinton and Barac Obama campaigns.

Clinton and her husband, former President Bill Clinton, have campaigned a lot in the Hills. Bill was at Black Hills State University in Spearfish on Friday. He’s also made trips to the Pine Ridge Indian Reservation and Rapid City. Hillary was at Talley’s Restaurant this morning. She’s also made other appearance campaign appearances in Rapid City and in Kyle on the Pine Ridge Reservation.

Hillary Clinton, too, stopped at Rushmore, and she was asked the same question. “Why don’t you learn something about the monument?” she replied.
