Opinion: Measles is back — and becoming a midterm liability for Republicans

The United States has recorded more than 4,000 measles cases this year, the highest annual total since 1991, with six related deaths. Former Republican congressmen and physicians Larry Bucshon, a cardiothoracic surgeon, and Michael C. Burgess, an obstetrician-gynecologist, warn that the party's wavering statements on vaccines are becoming a liability for the midterm elections. A KFF poll shows more than 60% of respondents disapprove of the Trump administration's handling of vaccine policy, and Democrats lead Republicans on the issue 41% to 25%, a 16-point margin.
