Rasmussen Reports. 4/27. Likely voters. 4.5 percent. (No trend lines. No previous Rasmussen poll polled these specific ballot lines.)
Democratic Primary
Lieberman (D) 51
Lamont (D) 31
Three way race
Lieberman (I) 47
Lamont (D) 20
Streitz (R) 17
And as of this poll, 38 percent of Connecticut voters still don't know enough about Lamont to have an opinion about him, yet Lieberman is just barely over 51 percent.
It's clear running as an independent will be Lieberman's clearest path to reelection. And it's also clear that if Lieberman pulls that trigger, that 1) Reid will have to strip Lieberman of all committee assignments and replace him with real Democrats; and 2) it's also clear that the DSCC will be forced to support Lamont's efforts (at least rhetorically, if not financially).
I'll call it the Democrats' "Lieberman problem", because they so clearly won't want to do either of those things and will do whatever they can to shirk those responsibilities.
Meanwhile, Connecticut Bob gives CT rape victims a convenient walking map between hospitals. It's necessary, because Lieberman said ... let me just pull up the quote:
Lieberman said he believes hospitals that refuse to give contraceptives to rape victims for "principled reasons" shouldn't be forced to do so.
"In Connecticut, it shouldn't take more than a short ride to get to another hospital," he said.
