( CNN ) -- Sen. Barack Obama on Sunday tried to paint Sen. John McCain as a candidate who is out of touch with the middle class . Sen. Barack Obama speaks about the economy at a campaign event in Detroit , Michigan , on Sunday . Speaking about Friday 's presidential debate , Obama accused McCain of not addressing working families . `` We talked about the economy for 40 minutes , and not once did Sen. McCain talk about the struggles that middle class families are facing every day , '' Obama said at a campaign event in Detroit , Michigan . The economy took the lead in Friday night 's presidential debate , as both candidates highlighted their plans to bring the United States out of what some are describing as the worst financial crisis since the Great Depression . McCain on Sunday brushed off Obama 's latest line of attack , saying he has `` bigger things to worry about . '' `` Who does he think I was talking about when I said 'people on Main Street ' ? Who did he think I was talking about , about the necessity of helping the American taxpayers and income -- and Americans who are out there working and trying to keep their jobs ? '' he said on ABC 's `` This Week . '' `` I 've got bigger things to worry about than that . '' The Republican presidential candidate did address `` Main Street '' in the debate Friday night , saying that `` we 've got to fix the system '' because `` Main Street is paying a penalty for the excesses and greed in Washington , D.C. , and on Wall Street . '' Still , Obama 's campaign pointed out that McCain did n't specifically say `` middle class , '' during the debate . McCain 's campaign said Sunday that during the Michigan event , Obama `` ignored his [ Obama 's ] record of opposing middle class tax relief , opposing a competitive tax rate , and opposing a plan to incentivize new battery technology . '' The campaign said Obama 's `` talk about the middle class is much different than his record . '' During the debate , McCain repeatedly said Obama `` does n't understand '' key issues the country is facing , but at campaign events this weekend , Obama blasted McCain as the candidate who `` does n't get it . '' Watch the candidates ' plans for the upcoming week » . `` The truth is , through 90 minutes of debating , John McCain had a lot to say about me , but he had nothing to say about you . Not once did he say the words 'middle class . ' Not once did he talk about working families . I think Sen. McCain just does n't get it , '' Obama said Sunday . The Obama-Biden campaign continues that argument in a new ad that will begin airing nationally on Monday . The ad says when it comes to the economy , McCain `` does n't get it . '' `` Number of minutes in debate : 90 , '' the announcer says as the words are typed across a blank screen . `` Number of times John McCain mentioned the middle class : Zero . '' The 30-second spot , `` Zero , '' includes portions of Friday night 's debate where Obama suggested McCain has followed President Bush on economic policy . Watch the ad » . A recent CNN/Opinion Research Corporation poll found when it comes to the economy , 47 percent of voters questioned said Republicans are more responsible for the current economic problems , while 24 percent said Democrats are more responsible . In response to the latest ad , the McCain campaign blasted Obama 's tax policy . `` John McCain repeatedly pointed to Sen. Obama 's vote in favor of higher taxes on families making just $ 42,000 a year , and his proposal for $ 860 billion in lavish new government spending which is a crushing burden on middle class families and the Main Street economy , '' spokesman Tucker Bounds said in a statement Saturday . `` If he was honest , Barack Obama knows he was unable to debate the merits of supporting higher taxes on the middle class , and bloated government spending during a looming economic crisis -- it 's simply indefensible . '' The McCain campaign is referring to a June 5 , 2008 , vote on a resolution ( Senate Concurrent Resolution 70 ) meant to outline the Senate 's budget priorities through 2013 , but the measure had no practical effect . According to a CNN review of the resolution , it assumes that most of the 2001 and 2003 tax cuts pushed by President Bush will expire in that time , which McCain says amounts to a tax increase . Obama and running mate Sen. Joe Biden voted `` yes '' on the resolution . McCain did not vote . However , the Democrats offered their own cuts in the 48-page resolution , which called for several tax cuts and breaks , including rolling back the alternative-minimum tax and the so-called `` marriage penalty . '' According to an analysis by the independent Tax Policy Center , the tax plan Obama has proposed during the campaign would increase taxes in 2009 on the wealthiest 20 percent of households , while offering tax cuts for the other 80 percent . CNN 's Kristi Keck and Emily Sherman contributed to this report .
