Working with SurveyUSA, an automated polling firm, Roll Call during the past two weeks ran polls on eight hotly contested Congressional races. The polls found that Democrats are narrowly but clearly ahead in two GOP-held districts, New Mexicos 1st, a marginal open seat, and Colorados 4th, where the incumbent, Rep. Marilyn Musgrave (R), seems to be in terrible jeopardy. Democrats also led in Floridas 21st district, held by Rep. Lincoln Diaz-Balart (R), though the lead was within the polls 4-point margin of error.
Two freshman Democratic Members who seized traditionally Republican districts in 2006 Reps. Christopher Carney (Pa.) and Nancy Boyda (Kan.) were also ahead, though not by comfortable margins, meaning that the GOP has a legitimate chance of winning those seats back.
The polls also offered some good news to House Republicans. In two open-seat races in GOP-held districts that the Democrats have talked boldly about competing Alabamas 2nd and Missouris 9th the Republican nominees held substantial leads. And the Republican was also leading in the race to replace retiring Rep. Jim Ramstad (R-Minn.), though his lead was within the margin of error, and that race in which a serious third-party candidate is competing is likely to be a tossup all the way to Election Day.
Polls can be controversial, and some of Roll Calls were no exception. Three of the eight polls brought swift reactions from campaigns and political operatives who disagreed with the results.
After Roll Call published its poll showing Carney with a 4-point lead over businessman Chris Hackett (R), Carneys campaign released a recent poll showing the incumbent with a 2-1 advantage.
When Roll Call showed Diaz-Balart trailing former Hialeah Mayor Raul Martinez (D) by 2 points despite the Republican lean of his Miami-area district, the Congressmans campaign blasted the SurveyUSA poll for interviewing too many Democrats. It also released its own poll from June that showed Diaz-Balart with a healthy lead.
But the most notable outcry came from several Democratic strategists who blasted Roll Calls poll on Alabamas 2nd district, which showed state Rep. Jay Love (R) with a 17-point lead over Montgomery Mayor Bobby Bright (D) in the race to replace retiring Rep. Terry Everett (R). Their chief complaint: The polls sample size of African-American voters found in the Roll Call poll to be 16 percent of the electorate was too small in a district where blacks represent more than 29 percent of the population, particularly in a year when the presidential candidacy of Sen. Barack Obama (D-Ill.) is expected to produce a larger-than-usual black turnout.
Democratic polls on the race that have not been made public show a much closer contest, and those polls assume a model using higher African-American turnout.
