DES MOINES, Iowa (AP) Michele Bachmann is quitting the Republican presidential campaign, saying she's ``decided to stand aside'' in the wake of her sixth place finish in the Iowa precinct caucuses.

Speaking deliberatively at a news conference in Des Moines, Bachmann said she had ``no regrets'' whatsoever and said she ran her race with integrity and will continue to fight for the causes she emphasized on the campaign trail.

It has been a long, deep slide for the Minnesota congresswoman, who enjoyed a high point in her campaign when she won a Republican straw poll in Ames, Iowa several months ago.

In her statement, Bachmann referred repeatedly to ``Obamacare'' and said the Republican Party must not miss a ``once-in-a-lifetime opportunity'' to repeal both the sweeping health care law under Obama's watch and the financial regulation law known as Dodd-Frank.
