I said mentioned as a candidate, not ran. People born when he last ran will be 32 on election day.
My biggest complaint about Warren, Sanders, and Biden is they had their turn in the sun and look where we are. In a perfect world it is time to see if new blood can improve us.
I read a book last year on the Battle of Britain. A section of the book dealt with the fall of France. The author pointed out the age differences between German and French political and military leaders. Germany looked at new and innovative solutions to the problem of war with France, France looked to the solutions of 1914-1918. That has helped sell me on the belief it is time to stop being afraid of new ideas. I do not buy any of the three listed are ready to offer anything except what has been offered since 1972 (when Biden first went to the Senate).
Wait...now the narrative you want to push is that Sanders and Warren aren't pushing new ideas? C'mon, Marv. Isn't that really primarily what they are doing? They're the ones being accused of dragging the debate left with all of their bold and "edgy" ideas.
The candidates all have their flaws, but there are a ton of good candidates competing for the nomination. I don't get all of the griping about the candidates. I get people's frustration with the President and the inability of the GOP to offer up a serious, competent candidate for the Presidency, but the Democrats are offering a wide variety of very serious and very competent candidates. My unsolicited advice is to spend less time musing on their shortcomings and spend more time exploring what's great about them...because there are lots of great things in those candidates that would make for exponentially better Presidents than the current one.
