Nonsense. The President will fill the larger stadium during *his* reelection campaign.
This venue is perfect for the Senator....and will be the largest crowd he's ever seen. 
Except ... the media is reporting it as Trump is holding a rally for Cruz in a closet. It maybe liberal media hype, but report after report and station after station is making a tremendous deal out of the size of stadium Trump booked for his rally for Cruz.
Yes Trump normally always packs a stadium and he's done so in the past couple of visits ... why oh why would he not do so for the hottest contest in the mid terms??
BTW haven't been able to find any stats on Cruz's past rallies by the numbers.
