For several years while Hillary Clinton was merely a government official it seems like the decades long Republican war against her had ended, but it was only lying dormant. For a while the GOP had a much bigger and juicier target in Barack Obama. Clinton was treated with a combination of political neglect or even respect.

Now that Republicans see attacking a lame duck provides only diminishing political returns they have once again set their sights squarely on Clinton. Yesterday’s Benghazi hearing was all about trying to tie blame to Clinton, as this new ad by American Crossroads makes clear.

With Clinton currently holding very strong poll numbers the Republican Party seems to have decided their best hope against her is to tear her down as early as possible. Don’t be surprised if this is the start of a three-year long operation.
