A new Washington Post poll of the national GOP race shows a significant improvement in the fortunes of John McCain, who rose 7 points from a Post poll last month. The new survey puts leader Rudy Giuliani at 33 percent, with McCain at 19, Thompson at 16, Romney at 11, and Huckabee at 9. The numbers are virtually unchanged from last month’s Post poll, except for McCain. That poll showed Giuliani at 34 percent, with Thompson at 17, McCain at 12, Romney at 11, and Huckabee at 8.
