If anyone Russia roots for on Twitter is disqualified Putin has an automatic veto over who runs for US president. The real test is in policy. Who increases the defense budget? Who vows to cut it? Who increases energy independence? Who decreases it? Or similar tests.
If this test seems wrong devise another. But "you will know them by their fruits. Do men gather grapes from thornbushes or figs from thistles?"
By applying the "fruits" test you can filter out Russian disinformation and separate the signal from the noise.
The long and short of it is the candidates should be evaluated on the basis of who they objectively are and not by any shade or praise Putin throws on them.
