A new video from Mitt Romney’s presidential campaign Tuesday hits Rick Perry on the topic of illegal immigration, doubling down on Romney’s previous remarks that Perry could pass for a Democrat.

“Maryland welcome[s] you. You’ll fit right in,” Romney tweeted Perry, along with the link to the video.
 
The Web video, titled “They agree,” plays up similarities between Perry, President Obama and Maryland Gov. Martin O’Malley (D). Romney’s campaign points out that earlier this month, O’Malley praised Perry for legislation he supported, as governor of Texas, extending in-state tuition at state colleges to illegal immigrants who graduated from a Texas high school.
 
“If you’re a United States citizen from any one of the other states, you have to pay $100,000 more [than an illegal resident of Texas],” Romney says in a debate clip included in the video. "That doesn't make sense to me."
