Election officials ‘look over our shoulders more’ as US political violence surges

Public officials lower on the ticket, who don't have Secret Service protection, say they are concerned after the gunman on Trump's golf course underscored the rising threat of violence

The second apparent attempt on Donald Trump's life on Sunday is the latest episode this year to underscore the way that the threat of violence has become ubiquitous for public officials in American life.

It is a threat that touches officials at every level, from presidential candidates like Trump, who have around-the-clock protection from the Secret Service, to lower level judges and election officials, who do not have that level of security.
