Via WKMG in Orlando:
The Democratic Senatorial Campaign Committee, which has backed Grayson's chief opponent, U.S. Rep. Patrick Murphy of Jupiter, and has no love lost over Grayson, didn't even mention the Orlando congressman by name in a statement released shortly after the announcement.
"Patrick Murphy has spent his career fighting for Florida families, women, seniors and the environment, and he has proven himself to be a hard-working and responsible representative for his constituents," DSCC Communications Director Justin Barasky said. "The contrast between Patrick Murphy and whichever Republican emerges from their chaotic primary will be stark, and we look forward to highlighting those differences."
Grayson's camp quickly fired back with an email titled "What the DSCC Should Have Said About Alan Grayson..." The email body read "...if they had any class." It included a copy of the Democratic National Committee's statements when Bernie Sanders, Martin O'Malley and Lincoln Chafee jumped into the presidential race against Hillary Clinton. DNC Chairwoman Debbie Wasserman Schultz welcomed their candidacies.
In a statement of his own, Murphy said, "I look forward to a clean, honest discussion of the issues in this primary.
"I have built a strong record of working together to get things done, while remaining true to core Democratic principles like protecting Social Security and Medicare, fighting for a woman's right to choose, and strengthening the middle class. I look forward to sharing that record with Floridians across the state."
He then followed up with a fund-raising pitch to his supporters.
