Ads sometimes help the underdog much more than they help the already-known incumbent - ads can put them both on equal footing if the volume is reasonable. I've discovered new small family restaurants I never would have noticed if I didn't get their postcard ads. Similarly, thanks to ads I've heard of new political candidates challenging long-time incumbent politicians - they may be spending much less than the incumbent but they could afford to write me a postcard. Maybe instead of a digital ban, there could be rationing on a per-user basis of how often they are repeatedly shown a political ad from the same faction. That way challengers can get their word in.
