Pro-life Democrats constitute 22 percent of the party but only 1.6 percent of the House Democratic Caucus, and that number may be set to drop further on Tuesday.
NBC News correspondent Steve Kornacki tweeted statistics from the group Democrats for Life showing the gaps between voters and representatives on abortion, noting pro-life Illinois Rep. Dan Lipinski (D.) is one of only three pro-life Democratic House members. Lipinski is running to retain his seat against pro-choice primary challenger Marie Newman, who has racked up endorsements from such left-wing stars as Sen. Bernie Sanders (I., Vt.).
"3 of 193 (1.6%) of House Dems are now anti-abortion, while according to Pew 22% of Democratic voters are," Kornacki said.
Kornacki also pointed out how the Democratic Party has shifted toward a unified hard line in favor of abortion. When Democrats last retook the House in 2007, they had 32 representatives who were against abortion, a far cry from the three now in office.
