Dean: "We have to grow the Democratic Party."
I won't say it was the worst thing clinton did, but one of the most ANNOYING things clinton did was to misuse the word "grow," as in "grow the economy."
Used in this sense, "grow" is not a transitive verb. You can "grow flowers," meaning to raise them, but you can't "grow the economy." Instead the correct usage is to say that "the economy grows," meaning gets larger.
This is like that other annoying political locution, "lesser developed nations." The correct usage is "less developed nations." "Lesser developed nations means "lesser nations" that happen to be developed.
Thus saith the grammar police.
