But there's evidence to the contrary as well. On two important issues, veterans' health and job training, congressional Republicans and Democrats have, with little notice, reached constructive bipartisan agreements.
These are both issues on which everyone agrees government should be involved. The country certainly owes something to veterans. And no one's proposing to eliminate job training programs altogether.
But government is also not doing a good job on either. The Veterans Affairs Department scandals have revealed a culture of lying and incompetence that comes as little surprise to those who have been scrutinizing the agency for many years.
And think-tank analysts both liberal and conservative have been concluding that government job training programs don't do much to prepare people for work or help them get jobs.
The best job training, many experts agree, is a job. But job-training programs have appeal to voters, and they do probably help some not insignificant number of people move ahead.
So there's an obvious need for legislation. And on these issues, as on so many others, Republicans and Democrats are in principled disagreement.
Nevertheless, Senate Veterans Affairs Chairman Bernie Sanders and House Veterans Affairs Chairman Jeff Miller managed this week to come to an agreement.
Sanders, a self-described Socialist, did not get all the money he wanted. And he accepted a provision that at least some veterans could get funds for medical treatment at private non-VA facilities.
Miller, who has being doing dogged oversight work that was not much noticed until last year when the Washington Examiner's Mark Flatten began highlighting it, made concessions as well.
The bill includes $5 billion for hiring more medical professionals and $1.7 billion for new VA facilities -- more than many House Republicans might like.
The Republican-controlled House overwhelmingly approved the bill Wednesday on a 420-5 vote, and the Democratic-majority Senate is expected to pass it quickly as well.
Both houses have already passed, the House by 415-6 and the Senate by 95-3, significant legislation reauthorizing and consolidating government job-training programs.
It eliminates 15 existing programs, consolidates others, gives states more flexibility and attempts to orient job training programs to "in-demand skills."
