It’s been barely a year since the shooting of House
Majority Whip Steve Scalise during congressional baseball
practice, and the story of the threats to Rep. Diane Black
were barely a blip in our news.
The shooting last June should have been a wake-up call for
our political discourse, but we’ve only been on a further
slide since then.
自己理解的意思大概是自从Steve Scalise被开枪已经过了一年
但这次Diane Black受到威胁的事件也只被简短的报导
这个枪击事件对政坛应该是个警钟
"but we’ve only been on a further slide since then."
以上这一句就不知道该怎么理解了, 我们只前进了一页??
另外其他部分如果理解有错, 还麻烦指正m(__)m谢谢
