The problem with your argument is Republicans do not want liberal tendencies. We call those people rinos. McCain and Romney are rinos. And they are rinos because they want to appease the media, which is wrong. The media nominated both McCain and Romney because they knew they would lose.
There were 10 million less republican voters in 2012 than 2008. This is because they didn't want to vote for a rino and saw little difference with him vs. Obama.
The truth is Obama was elected on lies and misrepresentations from him and the supporting media. Dems know what people like and they use it to get in office, then their agenda changes to what the really believe. If Dems ran on their agenda, they would not get elected, period. Just watch the mid term elections and how the Dems are going to distance themselves with Obama and Obamacare to get elected. The fact is, Dems lie to get elected.
And the dumb masses are finally realizing the lies.
Heres your first mistake.......the media didnt vote to nominate, neither did the media vote to elect.
Your second mistake is, your not thinking like a Lib or a Democrate....your underestimateing them. The GOPs major voting block are dying of old age or getting placed in nursing homes, where they cant vote.
You see the problem just like the majority of Republicans, as just a typical election loss. It wasnt just numbers and turnout.....it was about young voters, women voyers, minority voters, gay voters, poor voters VERSUS your typical RINO candidate and the Staunchly right wing voters who believe in same old crappy politics of Reagan.
