The Progressive-Democrats won a majority in the House, and the Republicans look like they’re going to expand their majority in the Senate. That looks like legislative paralysis in the next Congress.
However.
The next Congress won’t be sworn in until 3 January 2019. That gives two months for the present Congress, with Republican majorities in both houses, to get some remaining stuff done.
Top on that list in my august view is tax reform. This Congress needs to move to make permanent the individual income tax cuts that otherwise will expire in 2025. Get it done now, before the Progressive-Democrats, with their gridlock, take sufficient office to block the reform.
