Michigan’s Republican nominee for US Senate, Mike Rogers, commented on his now opponent, Democratic Socialists of America nominee, Abdul el-Sayed (formally, the Progressive-Democratic Party nominee), for the same seat.

The choice this November is simple: common sense or complete insanity. For more than 25 years, one party has controlled Michigan’s two Senate seats—and they’ve run our state into the ground. They’ve driven 200,000 manufacturing jobs out of Michigan. They’ve dropped our schools to 45th in the nation. They’ve saddled families with the highest utility rates in the Midwest. Working people are paying more, earning less, and getting left behind.

Rogers’ statement would have been just as effective, if not more so, had he left off the ad hominem phrasing after that colon. He’ll be much more effective if he sticks to the policy failures of the Progressive-Democratic Party and the destructive nature of the DSA’s goals—which include elimination of the Senate for which seat the two are competing—and the already empirically demonstrated failures of the economic policies which el-Sayed espouses.

Rogers does not need the ad hominem foolishness. Using that just diminishes him and dilutes his case when it isn’t distracting from it.
