93000 ticket requests for the Kentucky rally.
Compare that to Obama rallies for his first midterms, when he couldnt even fill a 13,000 hall, let alone have anything close to 93,000tucket requests.
From 2010:
However, in contrast with the 2008 election, when across the US an Obama rally was a hot ticket and people had to be turned away, he attracted only 8,000 to the 13,000 capacity stadium. When he appeared at a rally in the same city in 2008 two days before the White House election, 80,000 turned out.

If anything, Trumps rallies are attracting bigger and more enthusiastic crowds than even in 2016. I say look at the crowds as much as the polls. There will be no blue wave this November.
