Illinois Rep. Dan Lipinski, one of the most conservative Democrats in Congress. As recently as 2014, Lipinski responded to a candidate questionnaire by saying that he would support an amendment in the constitution to ban same-sex marriage.
Lipinski hasn't gotten any better in the age of Trump: This year alone, Lipinski was one of just three Democrats who voted in favor of a GOP bill to ban federal funding for abortion services. Lipinski has also voted to overturn an Obama-era Health and Human Services rule that prevented states from withholding funds to Planned Parenthood and other healthcare groups that also provide abortions.
But Lipinski has earned a serious primary challenge for the first time in a decade: marketing consultant Marie Newman, a local activist involved with anti-Trump groups like Indivisible.
Can you chip in $5 to help elect a true progressive in Marie Newman?
