U.S. Senator Bob Casey Jr. leads Republican challenger by two points in the U.S. Senate race in Pennsylvania, according to a new poll.
Susquehanna Polling and Research of Harrisburg found that the race remains a statistical toss-up since nine percent of likely voters remain undecided.
Casey led Smith 46-41 and 45-42 in SP&R polls conducted last month and by a 45-36 margin during a survey in July.
SP&R president Jim Lee said that Smith is making the race competitive because he has solidified the GOP base, but Casey is still pulling 19 percent of self-described conservatives, which will be a problem for the Allegheny County businessman if he can't win a bigger share of the conservative vote.
Lee said Casey is still appealing to conservatives in central Pennsylvania, an area where it is critical for Smith to post big gains.
Casey leads 78-14 among Democrats while Smith leads 79-11 among Republicans, according to the poll. Registered Independents lean toward Smith by a 41-37 margin while "swing" voters who say they split their tickets in most elections are breaking 49-37 for Smith.
The telephone poll of 725 likely voters was conducted October 4-6 and has a margin of error of plus-or-minus 3.7 percent.
