The Latin American Public Opinion Project at Vanderbilt has some brand new (October 2016-January 2017) survey data from Venezuela. Mariana Rodríguez and Liz Zechmeister just published a new AmericasBarometer Insights paper (it's been a while since one was published, so this was welcome). They show Venezuelans strongly disapprove of closing the legislature (a question they actually use in their normal battery, so obviously it's good to have in there).
As a matter of fact, over the past few years Venezuelans have increased their trust in the legislature:
We can reasonably argue that the executive branch attacks on the legislature have made it more popular. The authors further conclude that the recent attack will likely make Nicolás Maduro less popular. Since only 17% of Venezuelans think he is doing a "good" or "very good" job, he can't go a heck of a lot further down.
