Read this piece by an anonymous Democratic politico if you haven’t already. Anonymous says, in part:

The record shows that since the Second World War, the Hispanic community has supported Democrats for president ranging from a high of nearly 90 percent for their fellow Catholic JFK to a low of 60 percent for Mondale, McGovern, and Kerry, for an average of roughly 2 to 1 Democratic. So any amnesty plan will create more Democratic than Republican voters in the foreseeable future. It took the last wave of Catholic immigrants — from the Irish famine refugees of the 1840s and Southern/Eastern workers of the post-Civil War era — nearly a century to consider voting Republican for Ike in the 1950s. Now a similar scenario is being set up again.
