A pro-ObamaCare group on Monday announced it is launching a seven-figure advertising campaign aimed at protecting 20 House Democrats who could face tough reelections.

The ad campaign by Protect Our Care will highlight the Democrats’ work on health care and argue that Democratic lawmakers are protecting people with pre-existing conditions, an issue that helped the party win back the House in the 2018 midterm elections.

The 20 Democrats include a range of lawmakers such as Reps. Lauren Underwood (Ill.), Elissa Slotkin (Mich.) and Andy Kim (N.J.) who unseated Republicans last year, running in large part on health care.

Protect Our Care last week launched digital ads thanking the 20 lawmakers for voting in favor of a bill aimed at shoring up ObamaCare and lowering drug prices.

The measure combined bipartisan drug pricing bills with ObamaCare measures that were supported mainly by Democrats, leading Republicans to accuse Democrats of playing politics to scuttle a bipartisan vote on drug pricing.

Protect Our Care said that in addition to the new advertising campaign, it will also have staff on the ground in those House districts.
