Yes, but do you really think reparations of any sort will ever make it through Congress? I don't. If Keyes were Senator from Ill. he would likely never even cast a vote on the subject. The issue is in the courts. The courts have been and always will be the great undemocratic hope for unpopular liberal ideas. If reparations happen, activist judges will be to blame. Keyes is a non-issue on this subject, imo. His position is revealing, but just not relevant.
if the Democrats manage to regain control reparations could make it through. It's the ultimate form of pandering to a special interest group and most Democrat policy stems from pandering to special interest groups.
Anything that reveals a candidate's positions is relevant, these are your windows into how the person will govern if given the chance. Yes this particular issue might never come to vote, but something similar could.
