It should go for Romney. I expect Salt Lake County to be close, possibly tilt Democrat due to reverse coattails. CD-2 and the new CD-4 will both contain part of Salt Lake County and from what I've heard both may go Democratic. CD-2 is where Democrat Jim Matheson is currently representing, but is running for CD_4 this time around. He is expected to beat Republican rival and Saratoga Springs Mayor Mia Love. It has been a nasty race just in the 3 1/2 weeks I've been in Utah. Jim Matheson should carry CD-4 and CD-2 should remain with the Democrats. So, I expect Utah will have 2 R and 2 D in Congress, and those two D's should help push Obama barely over the top in Salt Lake County.
lol wat. All major prognosticators have UT-02 as Safe R, and I'm not aware of any evidence that non-negligible "reverse coattails" exist.
I haven't seen a single poll for UT-02, so though you may be right, you might also be wrong, since Salt Lake City (the liberal bastion in Utah) has about half of it's area in UT-02, and half in UT-04.
I only expect Summit county to go for Obama. Maybe Salt Lake if there was a huge explosion of Hispanic voters since 2010.
There have been a lot of Hispanic and otherwise non-white voters arriving in Salt Lake County, so I'd say your prediction is fairly accurate.
