A Pyrrhic victory. The Export/Import Bank is a small factor, compared to virtually everything else they deal with there.
What REALLY MATTERS is that they are pushing conservatives more and more into Trump’s hands (and Cruz, to a lesser extent) with these stunts. Yes, they win that vote, but sorry, they just added another 5 to 10 points to Trump’s level of support.
Trump is about as conservative as Arnold Schwarzenegger.
