To prevail on a claim of ineffective assistance of counsel under Strickland v. Washington, 466 U.S. 668, 104 S. Ct. 2052, 80 L. Ed. 2d 674 (1984), the defendant must show that counsels performance was deficient and that this deficient performance actually prejudiced his or her defense. In the context of a plea of guilty or no contest, to prevail on a claim of ineffective assistance of counsel, a defendant must allege facts showing a reasonable probability that he or she would have insisted on going to trial but for counsels errors. A claim of ineffective assistance of counsel presents a mixed question of law and fact. Whether counsel was deficient and whether the defendant was prejudiced are questions of law that an appellate court reviews independently of the lower courts decision, but the appellate court reviews factual findings for clear error. See State v. Gonzalez, 283 Neb. 1, 807 N.W.2d 759 (Neb. Jan. 13, 2012).
