There's already a downside. The GOP has had eight months to fulfill their campaign promises by passing a budget. Yet here we are. All the Democrats have to do now is wait it out. Eventually, the Republicans will cave and grant them some of the spending they are demanding.
And while we wait, hundreds of thousands of federal employees are losing their jobs, and agencies are being shut down.
That is real money that will not be spent, while we all know a budget is not real at all for the past 3 decades.
