Democrat presidential hopeful Joe Biden continues to raise eyebrows as he gaffes and missteps his way down the campaign trail. More recently, the 77-year-old Biden was seen running across the stage. I suppose Biden was running to show that at 77 he is still spry. Since 78-year-old Bernie Sanders suffered a heart attack last month, 71-year-old Liz Warren has even taken to running around.

Biden was in Iowa the other day but thought he was in Ohio. I suppose when you travel a lot, it can be difficult to keep straight where you are. But it's probably a good idea when you are asking residents of those states to vote for you.

Video footage shows Biden walking in circles on the stage in Iowa, and at one point he stops for 18 seconds with his back to the audience and addresses a curtain at the rear of the stage. Life Zette says at times Biden seems to think he is still vice president and that Barack Obama is still president.

A number of folks have raised concerns about Biden and whether he still has what it takes to handle the rigors of the presidency. Some of his antics are laughable until you think of him perhaps in a crisis situation as commander-in-chief.

What is worrisome to me is not so much that Biden is losing his grasp on reality but that his handlers and the DNC know he is. They see his behavior. If Biden is their frontman, who is pulling his strings and who would be running the country while he wanders through fantasyland?

I worry about who would be making decisions on behalf of the nation while pulling Biden's strings. It is frightening to imagine, especially given what we have seen of the Justice Department in recent years.
