One of the most interesting aspects of these polls is the gap emerging on
SF’s likely performance in the Euros - notably with respect to
FG and
SF. TNS-MRBI have Mary-Lou McDonald on 14% in Dublin, outpolling Eoin Ryan on 11% while Eibhlin Byrne trails on 5%. Yet Red C, which breaks down a much smaller sample of 1,000 into regional-samples of 200 or even less has
SF on just 7% in the capital, prompting Richard Colwell to state in the Sunday Business Post: “makes it appear likely that the party will lose its European seat.”. Likewise with Libertas, Red C have the party on 5% in Northwest, compared to 9% in the Irish Times poll. Likewise while TNS-MRBI has
FG on 38% in a General Election, Red C have them on 34% in a general and local elections, but at just 32% in the Euro elections, where support for Fianna Fáil rises to 25% relative to 22% in the other contests. In part, this reflects the tendency for Euro elections to gravitate to some extent around strong personalities as opposed to mere party-allegiance. Given the larger sample-sizes by TNS-MRBI (2000 nationally and 500 at constituency-level relative to 1001 and approx 200 per euro constituency for Red C), I would afford the Irish Times poll more credibility. In the 2007 election, I was convinced that Red C was closer to the outcome because the people behind them had worked in ICM which had the most accurate poll of the 2002 election, but this was proven incorrect (
FF won 41% in TNS-MRBI but just 38% in Red C on the day before the General Election). The Red C euro-poll also suffers from failure to ask respondants about specific candidates.
