( CNN ) -- Over the past couple of weeks , I have been asking random people who identify as Republicans if they trust Mitt Romney , and each of them gave me an answer like this -- `` I trust him more than I trust Obama . '' It 's just a long winded way of saying `` no . '' They said they did want to see his taxes . They said they have reservations about a major tax plan lacking specifics . Some said they saw the video of him describing himself as a pro-abortion rights moderate ; others knew that in the hardcover version of his book `` No Apology , '' he expressed pride in Romneycare and believed that `` we can accomplish the same thing for everyone in the country . '' They know he flip flops . Misspeaks . Lies . And yet , their dislike of President Barack Obama is so strong that they 're willing to overlook that whole character thing and swallow the bitter pill that is Romney . How can they do that , you say ? Well for starters , Obama is n't exactly a rock of Gibraltar himself . Politifact 's `` Obameter '' has been keeping track of the more than 500 promises the president made during the 2008 campaign and found thus far he 's kept 37 % of them . He 's broken 16 % , compromised on 14 % and is still working on another 22 % . So even though Romney smells , Obama 's not exactly lilacs . He promised to address gun control . He has n't . He promised to close Gitmo . It 's still open . Obama was for gay marriage , then he was against it , and now he 's for it again . If you believe his evolution was n't about politics , then you probably believe Jimmy Carter was robbed in 1980 . This is why some Republicans are willing to vote for a guy they may not trust : He 's viewed as the lesser of two evils . But pointing out the evils in the other party does nothing to address the evils in their own . Here 's the thing : The question of trusting Mitt Romney has nothing to do with Barack Obama . It 's about Romney . Voters might not like to think about that too much , but they need to look beyond campaign sleight of hand to give it some serious thought because the future of the middle class depends on it . This week , both Romney and VP hopeful Paul Ryan have been touting a multitrillion dollar tax-cutting plan with no details , essentially asking voters to take it on faith that it 'll all work out . Many conservative pundits , including George Will , say Romney 's math -- where it exists -- is a bit fuzzy and all Romney can say is `` trust me . '' So again , I ask Republicans : Do you ? Not in comparison to Obama , but in comparison to your understanding of the word trust . Knowing what you know -- and do n't know . Because if he wins , saying `` I trust him more than I trust Obama '' is not going to help matters in January . It 's not going to protect the middle class ' ability to write off the interest on their mortgages or deduct charitable giving . Romney said the plan wo n't touch those deductions , but he wo n't tell us which deductions it will touch . Trust him with our taxes , he says . And yet , he wo n't trust us to even look at his . At the Republican National Convention , Mitt 's wife , Ann , painted a picture of their early years together as if the two of them were barely getting by . And then an old Boston Globe interview surfaced in which she said `` we were happy , studying hard . Neither one of us had a job , because Mitt had enough of an investment from stock that we could sell off a little at a time . '' Realizing that struggling college students work and do n't usually live off investments , she backed away from her earlier characterization , telling `` Meet the Press '' later that , `` Mitt and I do recognize that we have not had a financial struggle in our lives . '' Uhm ... you do know that she did n't just realize this , right ? You do know that her speech was designed to manipulate voters in an attempt to paint her husband as a regular Joe , a guy just like them , someone they could trust . So ... do you ? Do you trust Mitt Romney ? Obama has only kept 37 % of his promises . But Politifact 's GOP Pledge-O-Meter , which they describe as having followed `` dozens of promises made in 2010 by Republican leaders '' and in their Pledge to America , found that the GOP has only kept 19 % of its promises . If you ca n't trust a guy who has only kept 37 % of his promises , how do you trust leaders that have only kept 19 % of theirs ? Better yet , how do you trust a guy , who as governor of Massachusetts , signed an assault weapon ban in 2004 , reiterated his support for a ban in 2007 and then shows up at an NRA convention in 2012 talking like some sort of John Wayne wannabe ? I do n't think you can . Which I guess is why many Republicans have a hard time saying they do . The opinions expressed in this commentary are solely those of LZ Granderson .
LZ : Asked if they trust Romney , a group of Republicans replied , ` ` More than Obama '' He says Romney f ##s and lies ; he wants us to trust him on tax plan he wo n't do . He says Obama has also broken promises , changed politics , but GOP track record worse . Granderson : The Republicans see early Obama as humble to faux - relate to voters .
