A first-time candidate and former coal mining executive, Smith has invested millions of dollars of his own money into his Senate campaign. He announced Tuesday that he loaned his campaign another $10 million during the third quarter, leaving him with more than $7 million in his campaign account at the end of September. Smith has significantly outpaced Casey in ad buys, although the senator has ramped up his spending in the last few weeks. Casey finished September with $5.2 million in the bank, after raising $1.5 million during the third quarter. The race has received limited attention in the local and national press, due to a perception that Casey held a commanding lead over Smith. Casey and Smith agreed Friday to participate in one debate, which is scheduled for Oct. 26. The Quinnipiac poll, conducted Oct. 12 through Oct. 14, surveyed 1,519 likely voters, for a margin of error of plus-or-minus 2.5 percentage points. The Muhlenberg College/Allentown Morning Call poll surveyed 438 likely voters between Oct. 10 through Oct. 14. It has a margin of error of plus-or-minus 5 percentage points.
