In the last 8 months DJT has twice filled,to overflowing,an arena in tiny New Hampshire that holds 11,000.He could easily get a lot more than that in a large state like North Carolina.
Just imagine the turnout in San Diego or a city in the San Joaquin Valley. Heads would explode and it would panic the Democrats into spending money they don't have to hold on to a "safe" state. And that would go for the down-ticket pols as well.
