Romney leads in second NH poll

For the second week in a row, former Massachusetts governor Mitt Romney is leading in a poll of New Hampshire Republicans.

Romney leads the new Zogby poll with 35 percent, solidly ahead of John McCain and Rudy Giuliani, who were tied at 19 percent.

The poll sampled 500 likely voters and had a margin of error of 4.5 percent.

A poll last week by Survey USA had showed a similar lead for Romney in New Hampshire.

In the Zogby poll, Romney's 35 percent is up from his 25 percent standing in April. McCain’s support has dropped from 25 percent to 19 percent, while Giuliani has held steady at 19 percent.
