(CNN) - As Barack Obama took to the trail in Michigan on Monday, the state's Republican party released a web ad needling him over his decision not to campaign in Michigan during the Democratic primary season - a line of attack Hillary Clinton warned of throughout her own presidential bid.
"Why did you boycott Michigan for so long?," the web ad asks. "You stiffed our voters."
The nearly two-minute long video proceeds to highlight Obama's "bitter" comments from a San Francisco fundraiser earlier this year.
"You insulted our way of life," the ad says, displaying assorted images of hunters and churchgoers.
A blog post on the Michigan GOP's Web site said the ad was created "to remind Michigan voters that when they wanted to hear from Barack Obama, he took every opportunity to thumb his nose at them."
In her push to have the disputed Michigan and Florida delegations seated in full, Clinton regularly argued that in a general election, Republicans would hammer Obama for his reluctance to do the same.
"If the Democrats send a message that we don't care about your votes, I'm sure John McCain and the Republicans would be happy to have them," Clinton said at a campaign stop in Detroit in March. "In fact, the Republicans will argue that Michigan and Florida voters shouldn't trust the Democrats to look out for them when we wont even listen to you."
Obama removed his name from the primary ballot in Michigan last year, a decision that led to a long-running debate with Hillary Clinton's campaign over the how to fairly count the votes from that state's unsanctioned Democratic contest.
Clinton won the uncontested Michigan vote in January with 55 percent of the vote, beating out "Uncommitted," which netted 40 percent. Earlier this month, the Democratic National Committee voted to seat the full Michigan delegation with half a vote each, allocating 69 delegate votes to Clinton and 59 to Obama.
