The McCain campaign released another negative spot this morning. The ad, titled "Painful," takes another swipe at Obama's celebrity and then accuses him of wanting to tax "your life savings" and "your family."

The ad seems to target women voters; several of the clips show moms with kids, and there's also footage of a female senior citizen and a shot of two women working in a flower shop.

The nonpartisan website Factcheck.org has criticized McCain in the past for similar allegations that Obama would raise taxes on small businesses and middle-class families.

Obama campaign spokesman Hari Sevugan responds:

This ad is a lie, and it's part of the old, tired politics of a party in Washington that has run out of ideas and run out of steam. Even though a host of independent, nonpartisan organizations have said this attack isn't true, Senator McCain continues to lie about Senator Obama's plan to give 95% of all families a tax cut of $1,000, and not raise taxes for those making under $250,000 a single dime. The reason so many families are hurting today is because we've had eight years of failed Bush policies that Senator McCain wants to continue for another four, and that's what Barack Obama will change as President.
