The US Chamber of Commerce is out with an ad reminding us that that Slaughter voted for Obamacare:

The CSEA is out with an ad reminding us that Maggie Brooks opposes Obamacare:

As with any ads released to the media and embedded in web pages, the question is whether they’re released to get some free media, or if someone’s going to pay to run them on actual TV stations. The CSEA ad is just red meat for its members, so I doubt it will be aired anywhere. The Chamber claims that it is buying some ad time, but my guess is that this, too, is a symbolic ad buy.

Update: Sean Carroll of 13-WHAM wrote to say that the Chamber ad is up and running in Rochester, certainly against Kathy Hochul from neighboring (current) NY-26.
