More than four dozen House members from both parties will tell party leaders Thursday that it’s time to put a halt to the increasingly invasive tactics of campaign trackers.

“Over the last few election cycles, the use of trackers has increased. Sometimes it even borders on stalking,” a letter to be delivered to Democratic Congressional Campaign Committee Chairman Steve Israel (D-N.Y.) and National Republican Congressional Committee Chairman Pete Sessions (R-Texas) states. “We believe filing candidates, sometimes with hidden cameras, while they take care of routine family activities like grocery shopping and posting videos of their private residences is a step too far.”

Reps. Reid Ribble (R-Wis.) said he and Dennis Kucinich (D-Ohio), the authors, had collected around 50 signatures — about 35 Republicans and 15 Democrats — as of Wednesday night for the missive. It came in response to a POLITICO story last month that revealed Democratic trackers have been filming the homes of Republican members and candidates and placing the raw footage on YouTube…

“This ‘nonstop’ ratcheting up of this tactic leads to what? And that is exactly our concern — that in an effort to inform, it has escalated to an effort to intimidate,” Ribble and Kucinich’s letter adds.
