No. The article above is *reporting* that five Democrats sided with Republicans in *support* of the AZ law SB1070. They can't stop the justice department from suing on behalf of the U.S. The lawsuit continues unless the justice department decides to drop it, and that is unlikly. The amendment was intended to refuse funds for the lawsuit. The concerning issue is that these Democrats seem to be against everything the White House does: Healthcare, Energy and Climate legislation, immigration reform, etc.
