Most diehard Republicans I know say they could at least stomach seeing Obama on TV for the next 4 years. OTOH, the thought of Hillary's grating voice, her plastic affect, and the general sliminess of Her Highness makes even the most lukewarm Republican want to crawl across ground glass to vote against her (with a few notable exceptions, mostly found on this website, who seem to think that a Hillary would "teach the Republicans a lesson").
Initially I would have agreed with you that he can at least be stomached. Not now. Have you seen him speak lately? When hes not seeming to chide the audience and country hes talking about himself like hes getting measured to be added to Mt. Rushmore.
Can they stomach a Justice Cornell West?
