Gardner has talked before about how abortion businesses unfairly target minority communities and how black women have abortions at much higher rates than white women or Hispanics.
But Gardner says the last straw for her is the recent controversy surrounding Obama's votes in the Illinois legislature against bills that would have protected babies who survive botched abortions.
"Barack Obama is an extremist who, in supporting what amounts to infanticide, would like to see all of us stand idle--twiddling our thumbs as unplanned children, who are born alive, die this terrible death," she told LifeNews.com Thursday.
"We must realize this is definitely part of Mr. Obama's plan for America," Gardner explains. "But it is definitely not mine. In my America, all voices shout, 'No We Can't!' and 'No We Won't!'"
Gardner is also troubled by Obama's refusal to admit that he voted against the Born Alive Infants Protection Act even after his own legislative committee adopted an amendment he now says would have made it possible for him to vote for the bill.
"It's hard to believe that this man who wants to hold the highest office in this land would not only oppose legislation to protect children born alive, but would then lie about it for four years stating that he didn't oppose it," she says.
"For four years, Obama misrepresented his vote, saying that the bill he opposed in the Illinois State Senate was different from the bill that was passed by the U.S. Senate and signed into law by President Bush," she told LifeNews.com.
"Let's understand what opposing this important legislation means," she explains.
"Suppose that a woman goes to an abortion facility for an abortion and by some blessing the child survives--alive. Barack Obama has voted that the abortionist, medical staff, and anyone else in the room should stand by and watch the child die a horrible death--gasping for air--without lifting a finger to help him or her," she said.
Gardner says pro-life advocates have opposed pro-abortion presidential candidates in the past like John Kerry.
However, she points out that Kerry joined with every other member of the Senate in supporting the federal version of the bill that had the same language as the Illinois bill Obama opposed.
