I’m not crazy about either candidate from an age perspective and have real concerns about how we in the US have an aging problem in our government as a whole. but cognitive ability no not really, but who knows. we gotta get people like Grassley, McConnell, Feinstein, Pelosi, Biden, Trump, etc, etc. outta office earlier and I would be in favor of a max age restriction at time of the election that matched the retirement age published by the IRS or something. Our population should be represented better from an age perspective. Right now I think the average age of a senator is like 58 with the average American being 39 and the average adult being 45.
