How many senators want to be remembered as having convicted beloved POTUS #44 or 45 for "impermissible policy" impoundment?

So I skimmed footnotes in House Trial Memorandum. This is where Schiff et al. itemize "evidence." The evidence seems to stored in digital facsimile in a House server (ea URL address) for sentators' review. My first pass found 70 unique exhibits on which the managers' argument for conviction rely (excluding sundry NYT press reports and DJT's prepared remark at public events). A gargantuan number of pages. Note that collection this material appears to ascertain motive and establish alleged Art. I, abuse of office ("bribery" conduct) by the POTUS, of which OMB/GAO/HPSCI correspondence.
