So, Bob Dole went against a conservative amendment that insisted illegal immigrants children couldn't receive an education. Essentially, Dole went on a Pete Wilson crusade against immigration. This lead to Bob Dole receiving a record low of Hispanic votes, only 21%. And this could have helped swing Florida and Arizona to Clinton. (Though Social Security helped him as well) Though I wonder how much this helped Dole among white voters. Many other western states trended to the Republicans that year. Really though, this reminds me alot of the anti immigrant Romney.
Non sequitur
Dole may have been anti-immigration, but that position did not result in his 21% vote amongst Hispanics. His predecessors Reagan and Bush did marginally better, considering the ratio of Hispanic support vs ratio of general population support.
Hispanics simply don't vote Republican.
