The two sides are waging a court battle.

Before the plebiscite, both sides waged intensive propaganda campaigns.

But each side in this dispute is waging a vigorous public campaign.

Both sides are waging campaigns playing to their strengths.

For several years the sides have waged war in the courts, and last week the Supreme Court announced it would consider the question.

The two sides have waged fierce publicity campaigns over the layoffs, competing for public support through advertisements.

Both sides waged all-out publicity campaigns, with billboards, radio and magazine ads.

Both sides are waging the political struggle remorselessly and it has been going on for years now.

And the two sides, instead of sorting it out, are just waging ad campaigns blaming each other in the NY media.
