Salt Lake Magazine's Glen Warchol says it's not as crazy as it sounds. He calls these Democrats posing as Republicans "Closet Dem's." He says they could nudge Utah politics back to the center by working within the Republican machine.
These Closet Dem's (CDs) could attend to Republican neighborhood caucuses and conventions and vote in GOP primaries. On these occasions, CD's could vote for the most moderate Republican and even elect each other in as county and state convention delegates. If nothing else, it would nudge the Utah GOP toward the edge of sanity.
Any moderate Republicans (aka RINOs, Republicans In Name Only) that the Closet Democrats elect would enjoy the same privileges as regular Utah rock-ribbed, crazy-assed Republicans (RRCARs) to attend otherwise closed legislative meetings, vote for state House and Senate leaders and even, maybe, be GOP leaders—it could happen. (Not to mention getting lunch and golf paid for them by lobbyists.)
For once, Democrats would actually have some impact on politics in Utah—even though they would no longer technically be Democrats.
