Required reading from Elizabeth Spiers. Two particularly salient excerpts:
By implying that impeachment in the Senate is the point, Pelosi denies the importance of the process itself—without which impeachment in the Senate wouldn’t happen in any case. And others have argued better and more persuasively than I could that Senate impeachment isn’t the primary or best reason to do it. Referral to the Senate may be in fact be unnecessary and undesirable.
[…]
A slim minority—just 19 percent—of polled opinion supported Richard Nixon’s impeachment at the outset of the Watergate scandal, and by the end of the House Judiciary Committee’s televised impeachment hearings, a strong majority supported it. And that shift in opinion translated into a massive wave of Democratic gains in the 1974 midterm balloting.
