After two live caller polls showed a much tighter Pennsylvania Senate race earlier this week, Democratic Sen. Bob Casey released an internal poll Friday showing him with a 13-point lead over GOP opponent Tom Smith.
The survey, conducted for Casey's campaign by Garin-Hart-Yang Research Group, shows the senator with 52 percent support to Smith's 39 percent.
Casey has been heavily favored in the race, but a number of recent polls have indicated that the contest has tightened, helped by the $17 million of personal wealth Smith is putting behind his bid. A Quinnipiac poll earlier this week showed a dead heat, with Casey beating Smith just 48 percent to 45 percent, and a Muhlenberg College/Allentown Morning Call poll put Casey's lead at just 41 percent to 39 percent.
A polling memo indicates that Casey has a 47 percent to 35 percent advantage among independent voters, and that he is winning white voters by five points (though it does not provide specific numbers).
The Garin-Hart-Yang Research Group poll surveyed 604 likely voters from Oct. 15-17, and has a margin of error of plus-or-minus 4 percentage points.
