As you know, it's very likely Utah will get a 4th congressional seat when the 2010 Census is officially finished.
Most probably assume it'll automatically go Republican. It probably could. However, the current plans also suggest the current second district (represented by center-right Democrat Jim Matheson) would become far more liberal than it currently is - which would force either Matheson to the left or force him out.
Here is a map that was endorsed by our former governor, now in the Obama administration, Jon Huntsman:
I know most have no f'n clue what county is what or where even Salt Lake City is located on this map.
The 2nd district incorporates the following counties:
Morgan
Salt Lake
Summit
Salt Lake County, home to Salt Lake City, is the county that is split between the 2nd and 4th seat.
The part in the newly formed 2nd district contains the most liberal part of Salt Lake County and Utah (Salt Lake City - if you'll remember, we elected Rocky Anderson twice).
Summit County is also home to Park City - which rivals Salt Lake in terms of liberalism.
Here is the breakdown of each county and how they voted in the 2008 presidential election:
Morgan: 79% for McCain
Summit: 57% for Obama
Salt Lake: 49% for Obama
Obama won two of the three counties in this proposed second district.
Now Morgan is a very conservative county. But it's also a very tiny county. It's only got 7,129 people, compared to 29,736 for Summit and over one million for Salt Lake.
Salt Lake went 49% for Obama, but Obama generally faired worse in the south-end of the county than he did up north where Salt Lake and its older, more blue-collar suburbs are located.
The south-end isn't part of the proposed 2nd district.
The original second congressional district looked very much like the proposed one. Unfortunately, I can't find a map of what it looked like - just that it incorporated all of SLC before gerrymandering divided the city & county up. In the 1996 election, Rocky Anderson lost a race for congress in that seat 55-42. Had that race happened today, he would lose by a huge margin because most of the district today is conservative and rural (which explains Matheson's right-ward tilt).
Ideally, Matheson would decide to not run for re-election when the new congressional district is created and allow the Democrats to nominate a far more liberal candidate who could win. Then Matheson could theoretically run in the newly created fourth district, which is very similar to the makeup of the current second congressional district.
That would give Utah two Democratic congresspeople and two Republicans. One would obviously be moderate, but he could be balanced out by a far more liberal candidate (say Rocky Anderson) in the newly updated 2nd district.
I believe Salt Lake City - the city, not the county - went overwhelmingly Obama in 2008. As you can see, so did Summit County. Those vote totals would easily offset any gains made by Republicans in the minimally populated Morgan County (only 4,021 people voted in Morgan County during the 2008 presidential election).
What does this all mean? Well if the district as proposed by Republicans here in Utah happens when the state receives its fourth congressional seat - I believe it could be won by a far more liberal candidate than Matheson. It also offers up the opportunity of getting another Democrat from the state if it's a moderate with good standing state-wide (since the fourth seat would take in part of Salt Lake County). Though that might be stretching. One of the best case scenarios, though, is a more liberal member of congress.
