What do Susan B. Anthony’s List and Nancy Pelosi have in common?

Dan Lipinski, it turns out. The anti-choice Democrat is running for re-election in Illinois’ 3rd District; he faces a primary challenge from a pro-choice woman, Marie Newman. Pelosi endorsed Lipinksi over Newman, and so has Susan B. Anthony’s List, an anti-choice group. McClatchy reports:

SBA List has dispatched 70 canvassers to the Illinois 3rd Congressional District and made a “six-figure investment” in digital ads and a mail campaign ahead of the Tuesday primary, according to an official with the group. Lipinski faces a fierce challenge from Marie Newman, a progressive advocate who has made the incumbent’s opposition to abortion rights central to her campaign.

Lipinski also voted against the Affordable Care Act and opposes marriage equality. Pelosi, who has previously decried “purity tests” applied to Democratic candidates, endorsed Lipinski on March 1. That pits her against EMILY’s List, the Human Rights Campaign, NARAL, SEIU and other members of her own party.

Polling shows Newman in a dead heat with Lipinski—meaning that Pelosi passed up a chance to support a viable, pro-choice candidate over an anti-gay, anti-choice incumbent in trouble.
