Remember, as of just a few weeks ago, this seat wasn’t even on the board. Then, for the first time in decades, MA-4 popped up in the “likely Democratic” column. And now, if you’ll pardon the pun, it’s moved a bit further to the right. I was thinking yesterday after I wrote that post about Bielat’s internal polling that maybe it wasn’t what it was cracked up to be: The topline number was conspicuously omitted (why would a pollster ever do that?) and the data was 10 days old (are the more recent numbers so grim that they had to leak stale ones?). In hindsight, I thought, they were probably trying to put the best face on an increasingly bad situation. But now here comes Cook with the best news I’ve heard all day — to the point where I wonder if, miracle of miracles, we might actually see this seat in the “toss up” column come Monday. My friends, the wave is upon us.
