A late note on Pia Kjærsgaard’s entry to the Swedish electoral campaign this Saturday. Unfortunately, I haven’t found a transcription of her speech at sd’s rally in Höganäs, so I will stick to making some general observations.
First, I don’t know of any studies into the use of foreign party leaders in national election campaigns. I suspect that the reason is that these appearances are generally seen as electorally irrelevant. Most voters only know national party leaders but will have a hard time recognising foreign party leaders. Just to test yourself: If you are Danish, name the leader of the Swedish Liberal Party. If you are Swedish, name the leader of the Danish Socialist Party. Googling is not allowed.
This leads to my second observation: Why invite foreign party leaders, if they have no visible impact on voters? After all, the Social Democrats have invited Norwegian Labour leader and prime minister Jens Stoltenberg and the Centre Party Finnish Centre Party leader and prime minister Mari Kiviniemi. (For some reason, nobody appears to have thought of inviting Danish PM Lars Løkke Rasmussen.)
My guess is that these guest appearances are mostly directed at the party activists. Seeing yourself as part of an international (successful) movement might spur activists during a campaign and that may again be a help in mobilising voters.
Kjærsgaard’s visit in Höganäs might bring a little more than that. sd is struggling to achieve electability and DF is not only electable, it has also been the partner of choice for the Danish Liberals (and to a lesser degree the Conservatives) since 2001. Appearing alongside Pia Kjærsgaard would give sd party leader Jimmie Åkesson a massive boost among party supporters, especially those who want sd to be a mainstream party, and help mobilise campaign workers in the last week of the campaign.
(I’m pretty much in line with Marie Demker as quoted in an interview with SvD here)
On the other hand, the visit might not be without risks for Kjærsgaard. After all, sd historically has its basis in the nationalist fringe and the border between sd and extremist currents has not always been clear. Even if she often uses a very potent rhetoric, Kjærsgaard is in fact a cautious party leader and she and the rest of the DF leadership have always been careful in distancing themselves from outright xenophobic or racist organisations or individuals. DF has no doubt vetted Åkesson and the sd leadership thoroughly before deciding to attend the sd arrangement.
The final question is if Pia Kjærsgaard’s appearing at an sd arrangement has any benefits for DF. There is of course an anti-Swedish sentiment among a large section of the nationalist opinion in Denmark (check out Ralf Pittelkow or any of Jyllands-Posten’s bloggers) and they would love to see sd enter the Swedish parliament as it would reassure them that the Swedes (or rather 5-6% of them) are just like us (or rather 13-15% of us).
Again, this is more of an elite (hah!) phenomenon, but I doubt if it has any direct effects on present of prospective DF voters.
