Acoording to
this, the number of "very active Wikipedians" last month was 3503. The number of Wikipedians with more than 5 edits is an order of magnitude larger.
The number of people who look up actors from obscure old TV shows on WP is probably many more orders of magnitude larger than the 5+ crowd. I doubt they're suddenly going to start calling their senators, unless they're tea party people in which case they'll probably call to support the bill because those lefty wikipedians are opposing it and therefore opposing it would be un-american.
