Zogby's May 15-16 poll of likely Republican voters in New Hampshire has Ron Paul at 3%, with a margin of error of ± 4.5%. (via Lew Rockwell's blog)
This is an interesting number to watch, because the first primary will be in the Free State. And, according to Zogby's Survey Methodology page, “more than 95% of the firm’s polls have come within 1% of actual election-day outcomes.”
Good thing for Paul the election isn't today.
