My head just exploded

As you know, a man named Billy Shears has kidnapped Josh Marshall in order to assume his identity. Shears/"Marshall" has just published a letter from reader RS, who believes that Hillary Clinton should never criticize Barack Obama in a primary.

RS thinks that any critical comments from Hillary will divide the Democratic electorate, and could provide the Republicans with ammunition.

Hillary's at fault.

This, from the same TPM which pushed the obscene "Hillary the racist" lie.
