It appears that Carolyn McCarthy has been right to be worried about CD-4 being redistricted out of existence. According to the Daily News:
“… State Senate and Assembly negotiators are looking at merging McCarthy’s Nassau County district into a Nassau-Queens district now held by fellow Dem Gary Ackerman, sources close to the planning said. McCarthy’s current district “collides” with Ackerman’s, making it a perfect candidate for merger, insiders said …”
That plus the fact that McCarthy is dumb as toast. She’s not a powerbroker. She’s nothing more than a single issue shill, and her one issue is becoming increasing unpopular with the public. In other words, she’s expendable.
