New York Times: “Many GOP candidates in tight races have tried to distance themselves from Mr. Trump’s policies, his behavior and the widespread allegations of self-dealing in his administration. Behind the scenes, some political advisers and outside Republican groups have warned the president’s aides that Mr. Trump could do more harm than good by holding rallies in battleground states with uncomfortably close races, according to people with knowledge of the conversations.”“But the president, under pressure and angry with naysayers, has dismissed polls that reflect his unpopularity, and has raged against unflattering stories that plunge him into a dark mood. Determined to win by turning the midterm season into a referendum on himself, he is set to headline rallies around the country all week, including in Ohio on Wednesday.”“Mr. Trump remains convinced that his dominant place in the Republican Party is enough to mitigate a tough political climate. But a grim mood has set in around the White House, which has been rocked by turnover, tension among internal factions and anxiety over what happens should Republicans lose legislative control in Washington.”
