Parallels in gun control and abortion legislation

From Russ Douthat's blog at the NYT (emphasis mine):

The pro-life movement has been pushing legislation along the lines of the bill that Davis filibustered for some time, but the sudden energy behind SB5 in Texas or the similar post-viability restrictions that passed the House of Representatives has a great deal to do with the recent trial of Kermit Gosnell, and the spotlight that case put on late-term abortion nationwide. In Texas and in Washington D.C., in other words, abortion opponents have basically tried to do what gun control advocates did after Newtown, and use a horror story to make the case for policies that have clear majority support but also face passionate opposition. And Davis and other abortion rights supporters have tried to do in Texas what gun rights supporters did in the United States Senate: Use countermajoritarian mechanisms to thwart a legislative push, and hope that with time and sufficiently passionate opposition the energy behind the bill will subside.

What the bill was attempting to do was require abortion facilities to meet the same standards required of other surgical facilities given the example of Gosnell's decrepit facility. In addition it also tried to restrict abortion after 20 weeks of pregnancy. Is that sort of limit something that Americans oppose? Not according to the Gallup polling agency which asserted that:

One of the clearest messages from Gallup trends is that Americans oppose late-term abortion.
