Most polls indicated a likely majority for a CDU/CSU-FDP coalition. As for other parties, those polls which explicitly included the PDS-WASG electoral alliance showed it above the 5% hurdle at between 7% and 8.5%. No poll showed any other parties, including far-right parties, near 5%, although far-right parties have in the past sometimes polled below their actual support due to unwillingness by voters to admit their support. In early August support for Angela Merkel declined considerably. Reasons for this included conflicts about the election program in and between the conservative parties (the CDU and the CSU), and arguments with their preferred coalition partner, the FDP, as well as embarrassing gaffes. At one point the media criticized Merkel for confusing net and gross income figures during a campaign speech. Following this, polls suggested that the CDU/CSU and FDP would only win 48% of votes between them, and thus would not be able to form a government. Further damage occurred when two prominent CDU/CSU candidates, Jörg Schönbohm and the CSU leader Edmund Stoiber, made insulting remarks about East Germans. These remarks not only alienated voters in Eastern Germany but also made some question the CDU/CSU's confidence in Merkel, as she herself grew up in the East. However, polls carried out by the "Süddeutsche Zeitung" in late August showed the CDU/CSU/FDP bloc back up at 51% of the vote. Predictions suggested that the opposing bloc of incumbent Chancellor Gerhard Schröder's ruling Social Democrats, the Greens and the country's recently formed left-wing Left Party (PDS/WASG alliance) would win a combined total of only 46%. The leaders of the SPD and the Greens, Schröder and Fischer, as well as the Left Party's front-runner Gregor Gysi said they opposed the idea of a "red-red-green" coalition. With polls remaining so close, speculation increased that (as in the elections of 1994, 1998 and 2002) a small number of overhang seats might significantly impact the election results. On Sunday 4 September, Schröder and Merkel met in a head-to-head debate which was broadcast by four of Germany's major private and public television networks. Although most commentators gave the initial edge to Merkel, polls soon showed that the general public disagreed and ranked Schröder the clear winner. Later analysis suggested that Merkel's support for a flat-tax proposal by Paul Kirchhof, the shadow Finance Minister, further undermined her credibility on economic affairs and gave the impression that the CDU's economic reforms would only benefit the very rich.
