Do endorsements really matter? If so, what target people are they trying to convince?
If Nancy Pelosi says she endorses Joe Biden, I think that the people who like Nancy Pelosi are probably already going to vote for Joe Biden anyway.
If Rush Limbaugh says he endorses President Trump, I think that the people who like Rush Limbaugh are probably already going to vote for President Trump also.
Whose mind are they trying to move????
