I'm-Unna

In Spencer's interview with the Federal Reserve, the Stanford economist interjected, "Are you actually from Utah?"

Yes, it's hard for Easterners to concede that civilized life exists west of Chicago. Wrong they are, but I will say that there some things are creeping into Spencer and mine's dialect that could have been dead giveaways this last weekend that we were not from D.C. Namely I'munna, as in, I'm going to (Spencer). Or fer, rather than for (that was me).

And does anyone else in the world have trouble pronouncing Potomac?
