While not a Trump supporter, I do agree with this.
Trump lost 3 elections in a row. After foiling his party's chance to take over congress in the last mid term election, Republicans were sick of him. No one was showing up at his rallys. He was down in the Republican primary polls. If Democrats and the media turned their backs on him and ignored him he'd be another Al Gore or John Kerry.
But instead they started dragging him into court on questionable cases. He deserved arrest over classified documents, but not Biden. He screamed unequal justice and rejuvenated his campaign.
And the more court battles he wins; SCOTUS unanimously overturning the Colorado court, NY appellate court so far partially overturning the NYC court ruling, the more his claims look justified and the more his poll numbers increase.
Democrats and the media should have turned their backs on him and let him wither on the vine of inattention.
