Call it logrolling or one hand washing the other, a generally recognized fact in Washington is that if you want something for your district, it pays to agree to the same thing for another guy’s district.

That point may have been lost on three Louisiana congressmen when they voted against a $50.5-billion relief package for the victims of Superstorm Sandy. The 2012 storm ravaged coastal communities in New Jersey and New York. Now they’re in the position of needing the same sort of aid for their own state. How will that play out?

The three lawmakers, all Republicans, are Rep. Steve Scalise (currently the House majority whip); Bill Cassidy, who moved up to the Senate last year; and John Fleming. They’re all likely exemplars of another Washington truism: fiscal responsibility is great, until it’s your own district that’s getting fiscally hammered. Then Job One becomes working to “help the residents of the threatened areas in their time of need.”...

Fleming, Scalise and Cassidy, by the way, are also climate change deniers, a sign that they’re unable to process evidence in front of their own eyes. Fleming has claimed that evidence of climate change is the product of a “radical environmental agenda.” Scalise has griped that it’s an effort by radicals “to prop up wave after wave of job-killing regulations that are leading to skyrocketing food and energy costs.” Cassidy in 2014 claimed that global temperatures had not risen in 15 years, which happened to be untrue. Remarkably, both Fleming and Cassidy are medical doctors.
