A group opposed to gay marriage said it will spend at least $2 million to oust seven New York state senators who changed their positions on gay marriage, The Associated Press reported.

The Washington-based National Organization for Marriage said in an email to supporters that it is committed to helping elect majorities in 2012 that support marriage as between only a man and a woman.

The group wants to ensure the Senate Republicans who broke party ranks understand that voting for gay marriage has consequences,' said the group's president, Brian Brown.

The four Republicans and three Democrats who changed their votes were vital in last week's passage of a gay marriage law in New York. Last Saturday, New York became the sixth (and largest) state to allow same-sex marriage.
