You cannot vehemently fight against your erstwhile base (on whom you have depended on to get out the Republican vote these many years in general elections for candidates that effectively cannot even wipe their own arses) and realistically expect them to just suck it up and hold their noses - again!
You GOPe types are risking everything, and you aren't going to get any new Hispanic voters because you want to capitulate on Amnesty for illegals. Not gonna happen. Instead you'll be complaining about the 5 million that sat it out, again. And then you'll start the whole cycle again for 2016. How many times do you have to get hit upside the head with a 2 by 4?
In Michigan the GOP isn’t challenging a single democrat held seat but they are challenging tea party held seats.
There is a republican challenging for the Dingell seat but he’s doing it without even token GOP support.
