“President Trump’s surprise diesel deal with Russia and decision to waive sanctions on Moscow have become a headache for Republican candidates with just two weeks to go before the midterms,” the Wall Street Journal reports.“In interviews and town halls, Republicans are being pressed on why now is the time to go soft on Vladimir Putin. Some of them are breaking with Trump rather than defend his string of Russia-friendly decisions.”“Diesel prices haven’t fallen significantly, adding to the challenge in an election heavily focused on affordability. The result is a new political hurdle for Republicans who are uncomfortable with the idea of easing sanctions on Putin’s Russia and have yet to see the hoped-for economic gains.”
