Hi Sam-
Where did you see that the March 11 town hall was a "Democratic Party meeting"? 
You are mistaken. 
The town hall was for all 30th district residents.
There are rules that put up a divide between legislative activities (paid for by state funds) and campaign activities (paid for with campaign donations). The town hall was an opportunity to serve all the 30th district constituents and used state resources (including staff time) to do so.
