Dear Zac Moffatt, Digital Director for the Mitt Romney campaign (@zacmoffatt):

Barack Obama lied in a recent Univision interview (link). While the War On Women is a great way to waste time with outrage, I think your general election opponent lying is more important. Calling Obama on yet another lie about immigration (see Obama immigration) would be a great way to undercut him on the issue and would also do a great public service by encouraging a more open debate about the issue.

Unfortunately, I can't find anything at Romney's site calling him out. I did find a couple of independent sites pointing out how the Democratic Party talking point Obama used is a lie, but that's not the same as something coming from Romney's campaign. I could easily show how Obama is lying (once again, see Obama immigration), but I wouldn't get any help with that from your campaign or from bloggers or those in the Tea Parties. So, I'm going to leave this up to you.

Here's the excerpt with the lie. I'm sure you'll get on this any day now:

[Enrique Acevedo of Univision]: Mr. President, excuse the personal note, but I grew up in a generation that has lived with the unfulfilled promise of immigration reform, and I’m not that young. And do you think if you are reelected you will be the President that gets it done? And can you promise you’ll do it within the first year of your second term?

Obama: I can promise that I will try to do it in the first year of my second term. I want to try this year. The challenge we’ve got on immigration reform is very simple. I’ve got a majority of Democrats who are prepared to vote for it, and I’ve got no Republicans who are prepared to vote for it. It’s worse than that. We now have a Republican nominee who said that the Arizona laws are a model for the country; that — and these are laws that potentially would allow someone to be stopped and picked up and asked where their citizenship papers are based on an assumption.

Acevedo: Racial profiling.

Obama: Very troublesome, and this is something that the Republican nominee has said should be a model for the country. So what we need is a change either of Congress or we need Republicans to change their mind, and I think this has to be an important debate during — throughout the country. What I’ve said to Latinos across the United States is that my passion for this issue is undiminished; that when it comes to, for example, the Dream Kids who have been raised as Americans and see themselves as Americans and want to serve their country or are willing to work hard in school and start businesses or work in our laboratories and in our businesses, it is shameful that we cannot get that done. And so I’m just going to keep on pushing as hard as I can, and what I’m going to be encouraging is the Latino community continue to ask every member of Congress where they stand on these issues, but the one thing that I think everybody needs to understand is that this is something I care deeply about. It’s personal to me, and I will do everything that I can to try to get it done. But ultimately I’m going to need Congress to help me.

Please don't respond in the normal way and pander; as discussed here and here that won't work. Instead, take a new tack and simply work to show potential Obama voters how he's lying to them.
