DENVER (AP) -- Abortion opponents could begin gathering signatures this week on a third Colorado ballot measure to challenge federal abortion rights.

The so-called "personhood" amendment would ban all abortions.

The measure is going to a state title board Wednesday. The board will decide on legal challenges to the language of the ballot measure.

The Personhood Colorado group could be cleared to begin gathering some 86,000 signatures needed for a third appearance on Colorado ballots.

Similar abortion bans on Colorado ballots in 2010 and 2008 lost badly.
