Struck the pose...partisan infighter - Tradução em português

At times, he struck the pose of an above-it-all leader urging Washington to compromise on a “balanced” agreement to cut the nation’s debt. Other times, he was a partisan infighter attacking the 2012 Republican presidential candidates and Congress. At times, he adopted the role of an everyman coming to the heartland to hear what locals had to say.

Struck the pose of an above-it-all leader seria atingiu uma pose de líder supremo? Ficou estranho o início dessa frase.

Partisan infighter seria "vira-casasa"? Alguém que briga contra o próprio partido?
