The latest salvo in the internal poll war in the 12th District -- where the candidates' numbers, oddly enough, always seem to give themselves the edge -- came Monday from the Democratic Congressional Campaign Committee, which put out a poll showing Democrat Mark Critz up, 48-41 percent, on Republican Tim Burns. 

The poll, by Grove Insight, surveyed 400 likely voters from Sept. 7-9 with a 4.9 percent margin of error, according to the DCCC, which released no further details or toplines.

“Voters already rejected Tim Burns once because he is out of touch with Western Pennsylvania," DCCC spokesman Shripal Shah wrote in an email. "While Mark Critz is fighting to bring jobs and economic development to Western Pennsylvania, Tim Burns is still pushing an agenda that only benefits millionaires like himself.  Tim Burns sold out jobs in Western Pennsylvania to get rich and his own company used tax breaks to ship American jobs overseas. As this poll shows, voters still understand that millionaire Tim Burns is wrong for Western Pennsylvania.”
