Every single 2016 presidential TV ad currently airing in a battleground state is either from Hillary Clinton’s campaign or the Democratic outside groups supporting her.

The opposition, by contrast, hasn’t spent a dime in these same battlegrounds — whether it’s Donald Trump’s campaign or Republican-leaning Super PACs.

So far in June, Clinton and the outside groups backing her have spent a total of $23.3 million on ads in the battleground states of Colorado, Florida, Iowa, Nevada New Hampshire, North Carolina, Ohio and Virginia, according to ad-spending data from SMG Delta. Some of the examples:

Republicans have spent $0 in these same eight states.

That's a 100 percent-to-0 percent advantage for Clinton and the Democrats in these battlegrounds.

By comparison, in June of 2012, President Barack Obama and the outside groups supporting him had spent $45 million in ads in 11 battleground states, while Mitt Romney and his allies — like Crossroads GPS and Americans for Prosperity — spent $38 million.

That was a 54 percent-to-46 percent edge for Democrats back then.
