(CNN) - Barack Obama has spent more than $8 million on Pennsylvania campaign spots over the past month – more than twice what Hillary Clinton has – as ad spending this year continues its record pace.
The Illinois senator’s presidential campaign had spent $8.1 million in the four-week period ending April 16, half of that in the critical – and pricey – Philadelphia ad market, according to an analysis conducted by TNS Media Intelligence/CMAG, CNN’s consultant on political advertising spending.
He is spending $400,000 a day, on a pace to exceed $10 million in ad spending – more than double Clinton’s $3.3 million in ad buys.
“Senator Obama’s campaign has done an excellent job of putting their fundraising advantage to work with record Pennsylvania ad buys, forcing Senator Clinton to spend valuable time and money in a state where she had a double-digit lead in the polls only a few weeks ago,” said Evan Tracey, chief operating officer of TNSMI/CMAG.
“If her own message connects with voters and pays off, it could be a big moral boost for the Clinton campaign. If not: the Obama strategy has paid off.”
Obama is also dominating the airwaves in upcoming primary states, spending $1.4 million in North Carolina and $1.8 million in Indiana, and has ads on the air in Oregon, according to the analysis. Clinton has made smaller buys in North Carolina and Indiana, and has not yet begun airing ads in Oregon.
