I’ve seen that 41% Hispanic support for Trump posted on a few web sites.
I believe George W. had 43% support amongst Hispanics in either 2000 or 2004.
Exit polling showed W winning 44% of Hispanics in 2004, but analysis from both the Left and Right showed that to be highly suspect. At most W won 40%, while Kerry won nearly 60%.
In 2000 W was in the mid 30s with Hispanics.
