Gallup's Jeffrey Jones put things succinctly. Extreme partisan views of presidents are the new norm in politics," he wrote in presenting new data on the partisan gulf in approval of President Trump. "The past 15 presidential years account for 14 of the top 15 most polarized years since Gallup began regularly measuring both job approval and party identification in the 1950s." Since 2010, the average presidential approval rating from an opposing party in a year hasn't topped 13 percent - and that was in 2010, when President Barack Obama's approval rating was still slipping from his post-inauguration high. Unlike Obama, Trump didn't enjoy a period of broader support at the time of his inauguration. Views of Trump have been remarkably consistent by party since he took office. There's some movement, but not a lot. Data released Tuesday by Quinnipiac University make that clear. In Quinnipiac's first poll of Trump's favorability ... about a fifth of Americans had no opinion of his job performance. In the next poll, taken in early February 2017, 42 percent approved of his performance (including 88 percent of Republicans), and 51 percent disapproved (including 90 percent of Democrats). In Tuesday's poll? Forty-one percent approve (including 86 percent of Republicans), and 55 percent disapprove (including 93 percent of Democrats). This is another interesting aspect of Trump's approval ratings: More poll respondents have strong views of his presidency, positive or negative, relative to any recent president.
