With Texas and Wisconsin the latest states to attempt limits on abortion, fewer voters than ever are calling themselves pro-choice, and the gap between pro-choice and pro-life voters is the narrowest yet.

A new Rasmussen Reports national telephone survey finds that 46% of Likely U.S. Voters now consider themselves pro-choice, the lowest finding in three years of regular surveying. Forty-three percent (43%) say they are pro-life, matching the highest finding to date. Eleven percent (11%) are undecided. (To see survey question wording, click here.)
