4 U.S. Senators should easily afford to chip in and hire a cleaning person to come in a couple of times a week.
When a persons politics are sleazy, I suppose we should expect their personal habits to be the same.
My mother, God rest her soul, trained me and my brothers that being clean and neat was not optional in our home. We all made our own beds, cleaned the bathroom, and never {unless you wanted to be beaten} left anything strewn about.
50+ years since that training, and I still have the same habits {and Mrs. Alaska thanks the memory of my mother daily}. My hunting camp is cleaner and neater than the squalor these pigs have chosen to live in.
For a great description of this mind set, and the relative philosophical difference between conservatives and liberals, read Gary Aldrich's 'Unlimited Access'.
He talked about how it was when the Bushes were in the White House, people wore clean, neat clothes (jacket and tie were mandatory if you entered the Oval Office), and offices were kept scrupulously clean.
When the Clintons took over, the place was a mess...pizza boxes with half eaten slices of pizza, sagging half inflated baloons from a parties weeks earlier, trash all over the place, slovenly appearance and so on.
I am not a neat freak by any means, but I do believe in a professional setting that it says a lot about people. You can take one look at their workspace and get an idea. It is not always 100% accurate, but it is a good indicator.
That, and how you treat people who work "below your station". The people working in White House cleaning staff, kitchen, etc. HATED the Clintons with a passion. And they thought the Bushes were great. I can only guess at how the Secret Service feels, but after Lurch cursed a Secret Service guy who tripped him up skiing, I am guessing they are not kindly disposed to Liberals.
