October is generally determination month for hot-race candidates, and now that it has begun prepare for some major swings in several political venues.
Recently, with Election Day coming in less than five weeks, we have seen polling that detects significant change in several Senate campaigns, all showing a shift away from the initial leader. With the Senate up for grabs, each race becomes critical and could itself determine whether Republicans or Democrats control the body in the new Congress. Today, we isolate four such campaigns.
In Connecticut, Quinnipiac University released its latest poll (Sept. 28-Oct. 2; 1,696 likely Connecticut voters, +/- 2.0 percent error factor) that finds Democrat Chris Murphy now trailing Republican Linda McMahon 47-48 percent. This is a surprising result and much different from the 48-42 percent Murphy lead that Public Policy Polling found just a week ago (801 likely voters, +/- 3.5 percent error factor). It is important to note that both polling firms have surveyed this race repeatedly. Having the opportunity to study another reputable firm’s results in order to bring a fresh perspective might provide us a better directional indicator.
Shifting to another hot race, we turn to Massachusetts and a recent poll by Opinion Dynamics for the consulting firm Mass Insight Global Partnerships. This rather flawed poll – because the sample size is less than 350 respondents statewide and the survey period is a long five days – posts Democrat Elizabeth Warren over GOP Sen. Scott Brown by a 48-44 percent clip. This same polling firm gave Brown a large 52-42 percent lead back in January. Last week, Rasmussen Reports also released their poll showing the candidates to be in a statistical tie at 48-48 percent (Sept. 24; 500 likely voters, 4.5% +/- error factor). Conversely, that very day, the Boston Globe publicized their data projecting Warren to be holding a five-point advantage over the freshman senator, 43-38 percent (502 likely voters, 4.4% +/- error factor). With continuous polling producing conflicting results it is clear this race is going to come down to the final hours.
Wisconsin continues to provide us with a close and hard-fought Senate race. Rep. Tammy Baldwin (D-WI-2) received a measurable bump in the wake of her speech at the Democratic Convention followed by an extensive early media advertising blitz, and polling indicates that the tide has turned in her favor. At least in the short term, Rep. Baldwin is now the clear front-runner over former four-term governor Tommy Thompson (R), after he consistently posted an advantage before and after the mid-August primary. Two recent polls show Baldwin leading: the first by Marquette University Law School showing a four-point edge, 48-44 percent (894 likely voters), and Real Clear Politics revealing a five-point advantage, 49-44 percent. Republicans, at one point, thought this seat would be a clear pickup opportunity, however, it is currently trending more Democratic. This polling trend could just as quickly snap back toward Thompson once he responds to the current line of attack being put forth against him.
Joining this see-saw Senate campaign group is the open seat race in Arizona. For months, Rep. Jeff Flake (R-AZ-6) had held a significant lead in all polling against Democratic nominee Richard Carmona, the former US Surgeon General in the George W. Bush administration. After consistently gaining ground on Flake after the Aug. 28 primary, Public Policy Polling, in their Oct. 1-3 poll of 595 likely Arizona voters, puts Carmona into the lead for the first time, albeit by a scant 45-43 percent margin.
It is clear, differing from what we have witnessed in the past four election cycles, that no tsunami wave is emerging for either party this year. As we turn the corner into the homestretch of campaign 2012, it is important to monitor all momentum changes as a barometer for predicting final outcomes.
