2012/2014 CO-6cd US House Race- Coffman-R vs Miklosi-D/Romanoff-D.

Mike Coffman-R won re-election to the CO-6cd US House seat in 2012 against State Representative Joe Miklosi-D by a 2 percent margin. 2012 was a Presidential Election year with Obama-D as the Democratic standard bearer. 2012 was also the first election year CO-6 became a swing district.
Two years later in 2014, Coffman-R won re-election against Andrew Romanoff-D and 2016 against Morgan Carroll-D by a 8 to 9 percent margin. 2014 was a Republican wave midterm election year. 2016 was a Presidential Election year with Hillary-D as the Democratic standard bearer.

If Romanoff-D ran for the CO-6cd US House seat in 2012, Could he have defeated Coffman-R?
