Clinton Pulling Away in "The Battle of Pennsylvania"

The last Zogby Poll ahead of today's Pennsylvania Democratic Primary shows Sen. Hillary Clinton pulling away from Barack Obama. The poll has Clinton now leading by 10 points, 51%-41%, but with things trending away from Obama in a big way. That sets up the potential for a big win for Clinton tonight. If she wins by more than 10 points, there will be no way for Obama to spin the defeat as a victory and will really bring into question his viability as national candidate who can defeat John McCain in November.

Yet, Obama has an insurmountable delegate lead, making it a virtual surety that he will be the Democratic Nominee. If doubts about his ability to win lead to the nomination being wrested away from him by Superdelegates, it will undoubtedly split the Democratic Party wide-open. Either scenario looks good for John McCain in November - a weak and flawed Obama candidacy, or a Clinton candidacy running with a torn-apart Democratic Party.

New York's Hillary Clinton continued to pull away from rival Barack Obama of Illinois as the campaigning in Pennsylvania ended and voters prepared to cast ballots today, the latest Newsmax/Zogby daily telephone tracking poll shows.

She now leads Obama, 51% to 41%, having gained three points over the past 24 hours as Obama lost one point, pushing her beyond the poll's margin of error to create a statistically significant lead for the first time in the Pennsylvania daily tracking poll.

Meanwhile, 6% remained undecided and another 3% said they preferred someone else in the two-day tracking poll. It was conducted April 20-21, 2008, using live operators working out of Zogby's on-site call center in Upstate New York, included 675 likely Democratic primary voters in Pennsylvania. It carries a margin of error of +/- 3.8 percentage points.
