Should The Senate Call Witnesses?

I dunno, man.
I'm tired of being jerked around / Kavanaughed by the Democrats.
But given the extraordinary importance of impeachment, needless to say I understand that important information basically sitting ready to hand ought to be examined...
Again, I basically won't be surprised if Trump is fairly far down the guilty spectrum. And, of course, he's a hot mess in many important respects.
But it's virtually impossible for me to side with the Dems now that they're dancing to the tune of the Orwellian left.
