Political analysts suggested that Le Pen's strong position in opinion polls was due to the absence of a primary in her party (consolidating her leadership), the news of the migrant crisis and terrorist attacks in France (reinforcing her political positions) and the very right-wing campaign of Nicolas Sarkozy in the Republican primary (enlarging her themes). In a 2016 interview with the BBC, Le Pen said that Donald Trump's victory in the US Presidential election would help her, saying that Trump had "made possible what had previously been presented as impossible". However, she said she would not officially launch her campaign before February 2017, waiting for the results of the Republican and Socialist primaries, and preferred to keep a low media profile and use thematic think tanks to expand and promote her political program. As a result, her rare media appearances attracted large audiences (2.3 million viewers for "Vie politique" on TF1 on 11 September 2016 and 4 million for "Une ambition intime" on M6 on 16 October).
