According to Rasmussen, 56 percent of respondents in a recent poll oppose the federal lawsuit filed against the Arizona immigration law, while 61 percent would favor a similar law in their state.

On the other hand, just 28 percent of respondents support the federal suit.

But perhaps the most salient result for the White House and Democrats in Washington:

Eighty-six percent (86%) of all Likely Voters say the immigration issue is at least somewhat important to how they will vote for Congress this November, with 55% who say it is Very Important.
Those who say the issue is Very Important to their vote are even more likely to oppose the government action. Seventy-two percent (72%) of those who rate the immigration issue Very Important to their vote disagree with the Justice Department challenge.
