I'm going to give some free advice to the Republicans nominate a Presidential candidate who will bring your base out you might lose a election without the moderates or independents you will lose a election without the base this was proven by both McCain and Romney both good decent men but men who did not enthuse the base. Look at the recent history Reagan could reve up the base so could Clinton both Bush's did enough to manage and Obama could this is one thing they all have in common along with the fact their opposition could not do it.
Horseshit.
Romney did not lose because the "base" stayed home.
Looking at the numbers.
Bush-43 got 62 million votes in 2004, the most votes a Republican has EVER gotten in raw numbers.
McCain got 59.5 million, while Romney got 60.5 million.
So. McCain got 2.5 less, and Romney got 1.5 less.
Nope, sorry, it was NOT that the "conservatives" failed to turn out.
Looking at the demographics, and you tell the tale.
White folks- Bush got 58% of the White vote, McCain got 54% of the White Vote, and Romney got 59% of the White vote. That indicates that all the conservative, white angry old people Romney was going to get out he did. Even those Evangelicals who screamed about Romney being a Mormon Heretic in 2008 suddenly loved themselves some Mormonism in 2012. We had to get the Negro out!!!
Sadly, though, White folks were 76% of the electorate in 2004, but they were only 72% of the electorate in 2012.
So then we have to look at the other races.
Okay. Blacks. Bush got 11% of the black vote, which wasn't that bad, and McCain got 4%. Romney improved that to 6%, which given Obama's status as the first black preisdent, is a bit of an improvement.
Hispanics are telling. Bush got 44% of the Hispanic vote in 2004. A credit to his attempts to buld bridges. McCain denounced his own immigration reform plans and embraced Tancredo and the Minutemen, and as a result, he got 31% of the Hispanic vote. Romney did even worse, denouncing the Dream Act and otherwise pandering to the right on this issue, and as a result, got 27% of the Hispanic vote.
Asians although being a small part of the electorate, tell a similar tale. Bush got 44% of them, McCain 35%, Romney sank to 26%.
So, long story short. Romney did not lose because "the Base" didn't show up. Romney lost because he didn't expand much beyond the base.
And the thing was, 2012 was winnable by the GOP. All they really had to do was point out that Obama failed to turn things around.
