The Rove/code pink incident was national news G-man. A tree fell, people heard.
I just did a search of google news for the phrase "rove code pink". It returned 294 results in 0.14 seconds.
Conversely, I searched google news for the phrase "tea party violence" and it returned 1,790 results.
That seems to indicate that the press wrote stories about the alleged tea party violence approximately six times for frequently.
Similarly, a searching google news for the phrase "left wing violence" generated only 755 results, whereas the phrase "right wing violence" generated 1,740 results (ie, more than a two to one margin).
Based on this it at least seems as if the press covers supposed conservative violence much more than supposed liberal violence.
