An organization of prominent conservative opponents of President Trump released a new ad on Wednesday targeting Sen. Susan Collins for her party-line votes at the opening of the president’s impeachment trial.
 “Senator Collins, you aren’t doing the job we elected you to do,” the 30-second ad, produced by the Lincoln Project, begins. “You’re a senator. Act like it.”
 On Tuesday, Collins voted for Senate Majority Leader Mitch McConnell’s resolution outlining rules for the impeachment trial, and against Democratic amendments to subpoena documents and witnesses from the White House, including acting White House chief of staff Mick Mulvaney and former national security adviser John Bolton. All of the Democratic motions failed, most by margins of 53-47, reflecting the makeup of the Senate.

Good. More constituents need to voice opposition to the way Republicans conduct themselves.
