About three-quarters of the President Barack Obama's advertising has been critical of Romney as Obama struggles to turn the election into a choice between himself and his rival
Washington: President Barack Obama’s re-election campaign has spent nearly $100 million on television commercials in key battleground states so far, unleashing a sustained early barrage designed to create lasting, negative impressions of Republican Mitt Romney before he and his allies ramp up for the November election.
The US president is chosen from state-by-state contests, rather than a nationwide popular vote. So battleground states— which are neither reliably Republican nor Democratic — are very important in tight elections, as this year’s presidential vote is expected to be.

With $100 million already spent, Mitt Romney has to watch out for more ads by Barack Obama targeting him
Reflecting campaign strategy, more than one-fifth of the president’s ad spending has been in Ohio, a state that looms as a must-win for Romney more so than for Obama. Florida ranks second and Virginia third, according to organizations that track media spending and other sources.
About three-quarters of the president’s advertising has been critical of Romney as Obama struggles to turn the election into a choice between himself and his rival, rather than a referendum on his own handling of the weak economy.
Obama’s television ad spending dwarfs the Romney campaign’s so far by a margin of 4-1 or more. It is at rough parity with the Republican challenger and several outside Republican-led organizations combined. They appear positioned to outspend the president and his allies this fall, perhaps heavily.
