A tightening race

From NBC's Domenico Montanaro
Some new polls out today… CNN/Opinion Research has Obama taking over the national lead, 49%-46%, over Clinton for the first time. McCain has widened his lead from a couple of weeks ago to 15-points over Romney, 44%-29%. Huckabee is third at 18%. The poll was conducted from Feb. 1-3 and has a margin of error of +/- 4.5% for the GOP and +/- 5% for the Dems.

Per the AP, "seven in 10 Republicans say they would be satisfied with McCain as nominee, six in 10 say so for Romney. Democrats' enthusiasm is higher: 79 percent said they would be satisfied with a Clinton nomination, 85 percent feel the same about Obama."

Obama and Clinton are tied in a new CBS News poll, 41%-41%, though Clinton leads 49%-31% among those who live in Feb. 5 states. Clinton led nationally just weeks ago in the poll by 15 points.

Obama also now leads Clinton by a thin margin, 46%-44%, in Massachusetts, according to a 7NEWS (WHDH-TV/NBC Boston)/Suffolk University poll out today. Romney leads McCain 50%-37%.

Per Suffolk's release, 43% of people said Sen. Ted Kennedy was the most influential endorsement (Bill Clinton got 23%). The poll was taken Feb. 1-3 and has a margin of error +/- 4.9%.
