Conservative outside spending groups are welcoming President Barack Obama to Charlotte, N.C., with a barrage of attack ads.

At least three conservative nonprofits and the Republican National Committee are running television and print ads as Obama prepares to give his acceptance speech for the presidential nomination at the Democratic National Convention in Charlotte Thursday night.

The Republican Jewish Coalition attacked the new Democratic platform that removed certain pro-Israel language from platforms of years passed — some of which was replaced.

It bought $75,000 worth of ad space in the Charlotte Observer highlighting the difference between the 2008 platform and the 2012 platform. One of the sticking points — that the platform removed a statement about Jerusalem being the capital of Israel — has since been reinstated, at Obama’s insistence, albeit amid some confusion, AP reported.

The ad is also slated to run next week in Jewish newspapers in Florida, Ohio, Pennsylvania and Nevada.

The nonprofit American Future Fund attempts to draw attention away from what Democrats call the Republicans’ “war on women” with the ad “What’s at Stake.”

The ad, airing in North Carolina, features pro-choice women saying a woman’s right to choose is not at stake in this election — the “future of America” is. The women say that is the reason they are voting for GOP presidential nominee Mitt Romney and running mate, Rep. Paul Ryan.

Americans for Prosperity takes the health care angle in North Carolina with a $5.8 million ad buy for “Replace,” which tells the story of a sick Canadian woman forced to seek medical treatment in the U.S. She says Canada’s government-run health care system failed her and that America’s current system saved her life.

Factcheck.org cites a Canadian Broacasting Corporation story in which a neurosurgeon says her condition, a type of benign cyst, is not fatal, as the woman claims, though her vision was at risk.

Spending by nonprofits on negative advertising has been ratcheting as the election looms closer. Nonprofits, unlike party committees and super PACs, do not release the names of the donors who pay for the ads.

To round out the barrage, the Republican National Committee goes after Obama on the economic recovery.

The web video “These Hands” tells the story of a struggling small business owner in High Point, N.C. She says that when she opened her new furniture store, she got more than 420 applications for five positions.

“That crystalizes, in my mind, that we’re on the wrong road,” Melanie McNamara says.
