During and after the final debate, McCain compared Obama's proposed policies to socialism and often invoked "Joe the Plumber" as a symbol of American small business dreams that would be thwarted by an Obama presidency. He barred using the Jeremiah Wright controversy in ads against Obama, but the campaign did frequently criticize Obama regarding his purported relationship with Bill Ayers. His rallies became increasingly vitriolic, with attendees denigrating Obama and displaying a growing anti-Muslim and anti-African-American sentiment. During a campaign rally in Minnesota, Gayle Quinnell, a McCain supporter, told him she did not trust Obama because "he's an Arab". McCain replied, "No ma'am. He's a decent family man, citizen, that I just happen to have disagreements with on fundamental issues." McCain's response was considered one of the finer moments of the campaign and was still being viewed several years later as a marker for civility in American politics, particularly in light of the anti-Muslim and anti-immigrant animus of the Donald Trump presidency. Meghan McCain said that she cannot "go a day without someone bringing up (that) moment," and noted that at the time "there were a lot of people really trying to get my dad to go (against Obama) with... you're a Muslim, you're not an American aspect of that," but that her father had refused. "I can remember thinking that it was a morally amazing and beautiful moment, but that maybe there would be people in the Republican Party that would be quite angry," she said.
