President Barack Obama is among the many marketers tweeting out Halloween-themed messages today, seizing the moment to urge eligible Americans to sign up for health coverage under the Affordable Care Act.

The official @BarackObama handle tweeted to its more than 39 million followers, "Don't let anyone scare you out of getting affordable health insurance," alluding to attacks made on Obamacare by congressional Republicans. It's accompanied by an image that shows a first-aid kit in the middle of spooky paraphernalia like a jack-o-lantern and a skull with the text, "Some people want to scare you out of getting affordable health insurance. Don't let them trick you."

Thanks to the Twitter redesign that displays photos attached to tweets in users' streams, the image -- essentially a display ad -- is getting plenty of visibility.

The same image was also tweeted out by Organizing for Action (formerly Obama for America), an advocacy group promoting the president's agenda that was born out of his presidential campaigns. That account has more than 292,000 followers.

The tweet makes no mention of the well documented technical problems experienced by visitors to Healthcare.gov.
