Pennsylvania’s Democratic primary election is just two weeks away, and a poll released… Pennsylvania’s Democratic primary election is just two weeks away, and a poll released yesterday shows Sen. Barack Obama locked in a tie with Sen. Hillary Clinton.

The poll, conducted by New Hampshire-based American Research Group Inc. surveyed a random sample of 600 registered Democrats in the state over the weekend and found the candidates dead even at 45 percent each.

Four percent of those polled said they would vote for someone else, while six percent said they are still undecided.

The poll has a margin of error of plus or minus four percent, according to ARG’s website.

A similar ARG poll taken March 26 and 27 showed Clinton at 51 percent and Obama at 39 percent with 8 percent undecided.

Other polls taken in the last two weeks show Obama trailing Clinton by as much as 10 percent, according to Pollster.com, a website that compiles data from multiple polling sources.
