According to exit poll data, Mitt Romney did well among New Hampshire Republicans and Republican-leaning "undeclared" voters who say immigration is their number one issue, trouncing McCain 56 percent to 19 percent. Unfortunately for Romney, only 23 percent of the Republican primary electorate said immigration was their most important issue. Among all other issues - the economy, Iraq, and terrorism - McCain won handily. Immigration topped the issue list in the Iowa entrance poll, but caucus-goers who said it was the most important issue went for Huckabee over Romney, 36 percent to 30 percent, despite Huckabee's record and Romney's ceaseless attacks on it. America's immigration laws are in need of reform and voters' concerns over illegal immigration ought to be addressed. But the Republican electorate doesn't seem ready to choose a presidential nominee based solely on his stance on "amnesty." And the endorsement of Tom Tancredo doesn't count for much.
