Meanwhile, it appears rational behavior may be contagious. In another surprising action, the House on Monday took steps to revive the Export-Import Bank, circumventing Republican leadership by means of the rarely-used discharge petition to get a bill extending the bank's charter on the floor. The Ex-Im is essential for promoting foreign trade and U.S. job creation, and given the strength of the discharge vote, its reauthorization, at least through 2019, seems likely. Now, if only a congressional embrace of common sense could include other pending measures of similar importance like extending the deadline for railroads to comply with federal safety mandates or authorizing a six-year transportation spending plan. Failure to act on either could be disastrous for the nation's transportation systems and ultimately, for the economy.
