Nearly everything is slowing, - all across the board. This is the rough spot that was predicted. How long is it going to last? Well, if Democrats obstruct - it will probably last longeer than needed.
The problem is the uncertainty. Who is going to invest money in anything with the future is so uncertain?
They need to make their cuts and get it over with.
They need at least another 4 weeks to even begin to predict how long this chaos/turmoil is going to last. My guess, for what it is worth, is that major uncertainty can last somewhere between another 6-24 months. That means at least a partial recession, possibly a full blow recession - before things get better.
I'm not sure how the government is going to keep people from losing their homes and starving. But, of course, they will certainly have to come up with some temporary fix, such as temporary unemployment payments - as after the 2008 financial crisis.
