Clinton swamping Trump with ads in battleground states

Hillary Clinton and her allies have outspent Donald Trump by more than $100 million on the airwaves in the battleground states that will determine the outcome of the election. 

An analysis by NBC News of data provided by Advertising Analytics shows the Clinton campaign outpacing Trump by a 4-to-1 margin on spending in Florida, Ohio, North Carolina, Pennsylvania, Nevada, Iowa, Virginia, Colorado and New Hampshire. 

{mosads}The study found the Clinton campaign running $113.3 million in ads in those states, with an additional $75.8 million coming from pro-Clinton outside groups, for a total of $189.1 million. 

The Trump campaign has spent only $27.3 million on ad buys in those states. The campaign has nearly been matched by the $22.5 million coming from pro-Trump outside groups, for a total of $49.8 million. 

Pro-Clinton forces have dumped the most cash in Florida, dropping more than $46 million into the state, compared to only $14 million for Trump. Clinton has a small lead in the polls there, edging Trump by 2.8 points in the RealClearPolitics average. 

In Pennsylvania — a traditionally blue state that is critical to Trump’s presidential hopes — the Republican presidential nominee is being outspent $17 million to $6 million. Recent polls show Clinton, the Democratic nominee, pulling away from Trump in the Keystone State, with a Monmouth University survey released Tuesday showing her up by 10 points. 

There are a couple of states where Trump leads despite being drowned out on the airwaves. 

In Ohio, Trump leads by about 3 points in the RCP average, despite being outspent $32 million to $9.6 million. 

In Iowa, pro-Clinton forces have dropped $11.4 million into the state. Trump leads comfortably there and hasn’t even spent $1 million yet. 

Trump’s unconventional campaign has relied heavily on earned media and the coverage of the massive rallies he holds across the country. 

But some Republicans are worried he’s not doing enough traditional campaign advertising, which they say could make the difference in a close election. 

Trump didn’t run his first television ad until August. His campaign spending ramped up significantly that month, although he started September sitting on $50 million.
