There are currently

four candidates in the upcoming GOP Primary for the US Senate seat currently held by Citizen Warren.
Per the Boston Globe, the rationale common to all four is, they may be able to do some business this fall on the basis of the presumed landslide Charlie Baker will rack up.  I'd like to quietly remind all and sundry that Governor Baker may well rack up a landslide this fall, (I can also envision him losing as well but no matter), and if he does it'll be because the Massachusetts Electorate has gotten into the habit of splitting it's tickets.  Thus a good chunk of those people voting for Charlie are also dead fixed on voting for Liz as well...Baker knows this, he isn't stupid, he is just a stiff, and as such I doubt he'll waste any time campaigning with the poor benighted jobber the GOP eventually nominates for the US Senate.
I mean why divide his base like that?
That Having been said I counsel no complacency this year, even if Warren has fourteen million large in the bank and a high approval rating she is still gonna come in for vicious treatment on the stump and on the airwaves as well.  That part of the fall campaign will be very ugly indeed, so lets all prepare for that however we must.
