The campaign of Rep. Mark Critz, D-Pa., released an internal poll on Monday showing their candidate within single digits of fellow Democratic Rep. Jason Altmire in the April 24 member-vs.-member primary, much closer than an Altmire internal last week.
The new Critz poll, conducted last Thursday through Sunday by the Democratic polling firm Global Strategy Group, shows Altmire narrowly head of Critz, 45 percent to 38 percent. The poll surveyed 400 likely Democratic primary voters and has a margin of error of plus-or-minus 4.9 percentage points.
The Altmire internal, conducted ten days prior by his firm, Anzalone Liszt Research, gave Altmire a 24-point lead, 55 percent to 31 percent.
Each campaign released a short memorandum about their respective surveys, so it is difficult to evaluate why the two polls might be so different. The Critz poll, however, showed Altmire leading among likely Democratic primary voters who reside in Altmire's current congressional district, 61 percent to 19 percent. The Altmire memo said Altmire led by a 61-point margin among his current constituents, modeling an electorate that consists of 64 percent of voters who resided in the old 4th District.
The two Democrats were drawn into the same Republican-leaning district by the GOP-controlled state legislature, which was forced to eliminate one congressional seat in reapportionment. Earlier this year, Critz tried to have Altmire removed from the ballot over the legitimacy of some of his certifying signatures, but a judge upheld Altmire's petitions.
