The odds of a government shutdown depend on a few factors. Currently, the odds of a shutdown don’t seem too high, but still possible. The deadline is rapidly approaching. The March 2018 government shutdown deadline is 11:59pm on March 23 2018. Most Federal employees and agencies will start being affected on the following Monday.
*update 3 – odds skyrocket after President Trump tweets that he is considering a veto.
I am considering a VETO of the Omnibus Spending Bill based on the fact that the 800,000 plus DACA recipients have been totally abandoned by the Democrats (not even mentioned in Bill) and the BORDER WALL, which is desperately needed for our National Defense, is not fully funded.

*update 2 – March 22 Bill passes House and debate ends in the Senate. Odds are that there will not be a government shutdown. The bill will likely pass in the Senate and be signed by President next Friday March 23 2018 ahead of the shutdown deadline.
*update 1 – March 21, the odds remain unchanged despite a bipartisan spending bill being released. There is a fair amount of opposition to the voluminous bill and very little time to avert a shutdown.
A major factor is the presence of the filibuster rule. A filibuster basically is a way for any senator to “talk a bill to death” unless 60 senators vote in favor of the bill. So, a vote for a continuing resolution or a longer-term funding bill would require 60 ayes.
Historically this rule, which was borrowed from ancient Romans, was a near certainty to continue as part of the US Senate tradition.
But President Trump and others have called for an end to the filibuster. Averting a government shutdown may be the high-stakes issue that causes the camel’s back to break.
With the ridiculous Filibuster Rule in the Senate, Republicans need 60 votes to pass legislation, rather than 51. Can’t get votes, END NOW!

This threat greatly reduces the risk of a longer-term government shutdown. While the filibuster rule is in effect the number of senators in the majority party is a large factor. With 51 Republican senators, there needs to be at least 9 Democrats in favor of the law.
The political climate and topical issues are another major factor. The two recent shutdowns [link] in February 2018 and January 2018 were partially due to immigration issues being a key negotiation point. It appears that Democrats have since backed off of immigration and DACA recipients as a key issue.
Gun control is another major issue. But this also might not have broad enough support to be a reason for shutting down the government.
Shutting down the government is a costly and disruptive activity.
But funding the government with politically poisonous attachments could end some legislators’ careers. The minority party hasn’t rallied around any rationale for a shutdown just yet. So the odds appear low.
There are some gambling markets that bet on the odds of a government shutdown. Predictit.org is one. The current odds there are around 20 percent.
I’d peg this as being a bit high today, but might be right tomorrow. With the March 2018 government shutdown deadline so soon, the odds will change rapidly.
Some more filibuster history
The second longest was by Alfonse D’Amato in 1986 during which he read the Washington D.C. phone book. This filibuster lasted nearly 24 hours as well.
