Senate Democrats recently blocked "Kate's Law," legislation intended to impose mandatory prison terms on illegal immigrants convicted of major felonies who have been deported but have again entered the United States illegally. The law was named after Kate Steinle, the young woman murdered this summer in San Francisco by just such a person.

Fifty-six percent (56%) of Likely U.S. Voters favor a five-year mandatory prison sentence for illegal immigrants convicted of major felonies who return to America after being deported. A new Rasmussen Reports national telephone survey finds that just 27% oppose such legislation, while 18% are undecided. (To see survey question wording, click here.)

Seventy-two percent (72%) of Republicans and 53% of voters not affiliated with either major political party favor a law like the proposed Kate's Law. Democrats agree by a much narrower 43% to 36% margin, with 21% undecided.

Fifty-nine percent (59%) of voters say the federal government is not aggressive enough in punishing illegal immigrants who commit felony crimes in this country. Just 22% believe the government is aggressive enough in punishing these individuals, but nearly as many (19%) are not sure.

Following Steinle's murder by an illegal immigrant from Mexico who had been deported several times and come back, 62% of voters said the U.S. Justice Department should take legal action against cities that provide sanctuary for illegal immigrants, and 58% said the federal government should cut off funding for those cities. Republicans in Congress included Kate's Law in legislation to cut funding to “sanctuary cities." President Obama threatened to veto the measure, but Senate Democrats stopped it procedurally.
