“Democratic lawmakers condemned Rinaldi’s behavior during a press conference following the altercation”
A pregnant negative: Republican lawmakers did NOT condemn Rinaldi’s behavior.
I wouldn’t call it Trumpland. This is EXACTLY what characterized the party (since they were the Democratic Party and the Democratic-Republicans before that). They have ALWAYS been founded on violent racism, in order to keep white wealthy anglos in power–over blacks, over poor whites, over Catholics, over Hispanics (especially in Texas). As TellTheTruth notes, the only difference here is that Rinaldi has an Italian name, and in the mid-nineteenth century, they were among the victims.
As Southern violence became more extreme leading up to the Civil War, maybe the silver lining in this cloud is that the GOPs violence wouldn’t be so pronounced if they weren’t seeing resistance to their Klan (i.e. white terrorism)-based ideology.
