Hillary Clinton may be narrowly ahead in some national polls, but Donald Trump has the enthusiasm advantage by a landslide.

Houston Chronicle reporter Mark Collette tweeted an astonishing video of the massive line of fans waiting in a half-mile long line in 97 degree temperatures.

As Collette notes, the heat index was actually a withering 117 degrees before the Houston, Texas event at The Woodlands.

The Chronicle’s Dylan Baddour reported a woman was taken away on a stretcher, presumably from heat exhaustion.

Jenna Johnson of the Washington Post tweeted a similar report about the lengthy line.

Buzz Feed’s Jim Dalrymple tweeted another shot of the line, which snaked around a corner:

Media reports indicate only a few protesters had assembled prior to the rally.
