The smarter option here is to just say nothing. The right has been brutalizing people for decades, so much so that we’ve all probably forgotten half the insane shit they’ve done. Politicians don’t have to outright condone ithe assassination attempt, but the right is a party of violence and isn’t entitled to “decorum”, they just treat it as a weakness.

Condeming the assassination attempt will earn them no good will with right-wingers, and won’t stop their inevitable “retaliation”.
