<p>Why is it “is” in: </p>
<p>To fear the act of impeachment and to think of it as a threat to the presidency IS to be misinformed… </p>
<p>Why is it “is” instead of “are” because two things are being referred to…</p>
<p>The subject is the act of fearing–singular.</p>
<p>But isn’t it the act of “fearing” and “thinking”?</p>
<p>“Is” is referring to “the act”, and act is singular.</p>
<p>Actually, it is because this sentence is in passive voice.</p>
<p>If you were to reword this sentence using active voice, it would be “To be misinformed IS…”</p>
<p>Hence, the subject is actually “To be misinformed”.</p>
