The good news is that Chuck Hassebrook has said that he will remain in the Senate race no matter who else joins. The bad news is that Bob Kerry may join (as of this publication date he has not yet declared, although his aides say he will).
Bob Kerry is a solid member of the .01%. He has written articles in a Nebraska newspaper "Prairie Fire" about the need to privatize social security. As Senator, he voted for Gramm-Leach-Bliley which overturned the Glass-Steagall act and eventually precipitated the Crash of '08. He defended this vote by saying "The concerns that we will have a meltdown like 1929 are dramatically overblown". His tenure as head of The New School was wracked with student strikes, faculty votes of no confidence and staff turnover. And, of course, he is an unrepentant war criminal (he led a massacre of a village in Vietnam; never apologizing for or even acknowledging it).
But it makes sense that he would be joining the race once Chuck Hassebrook declared. Hassebrook is the kind of progressive leader, respected in both rural and urban areas, that sends chills down the spines of the oligarchy. Kerry, as an oligarch with an occasional liberal position, will do his best to at least muddy the waters and keep Hassebrook from becoming a serious threat.
If Kerry declares, all the mainstream media and most of the money will go to him. Those of us who support the 99% will have to work at the grassroots to counter the oligarch echo chamber.
