I’m content to wait until after the elections in 2016 ... and then you can do the analysis on where the numbers came from, and let me know where I went wrong ... :-) ...
But the 'conventional wisdom' of the GOP-E has not won any elections. Romney lost because he was a liberal.
People will vote for conservatives. Republicans don't need liberal republicans to win elections. Republicans don't need liberal voters to win.
The liberal GOP-E doesn't want to hear that because it can cost their jobs, so that's why they spread the meme you just tried to spread.
