I've said it before, and I think it bears repeating.

In an election contest between yourself and right-winger, if you pass yourself off as right-wing 'light', you'll always lose.

Why?

Because voters may not like the right-winger, but they absolutely hate someone pretending to be something they're not.

Case in point -

Let’s consider the issue of health care, a supposedly high-ranking concern for “reluctant Trump voters.”
What would have happened if Ossoff came out for a national Medicare For All program?
In a suburban red district, what if he appealed to Republicans who dislike the Affordable Care Act? What if he adopted a message like Senator Bernie Sanders and National Nurses United that addressed the very real defects in the ACA?

What if he made the case that beating back the GOP’s cold-hearted health insurance bill—which not one state supports—was only possible with Medicare For All?

Instead, Ossoff ran with a health care message Clinton pushed. Ossoff said he would fight for “quality, affordable health care.” But what do these buzzwords mean in terms of policy?
Is it any wonder Republican voters tune this out? It is a vapid message. On the other hand, a message about workers saving thousands of dollars on premiums and employers saving more than $10,000 a year might intrigue voters.
