Actually, the GOP vote has been increasing for 20 years: 1996 Dole 37,816,307 2000 Bush 50,459,211 2004 Bush 59,130,092 2008 McCain 59,948,323 2012 Romney 60,265,579It is inaccurate to use the PARTIAL returns from election night to compare to the FINAL results from other years.
The problem with your numbers is that millions of independents who had voted for Obama in 2008 switched to Obama in 2012. Which means that millions of Republicans who voted for McCain in 2008 stayed home in 2008. In spite of the large swing in independent voters, Romney barely topped McCain’s mediocre effort from 2008. The GOP has a serious problem with its base and this purge of conservatives - including the disgraceful sell-out of Allan West - will ensure that the turnout of the base continues to erode.
Bush actually got 62M in 2004. So Romney’s totals were still below Bush’s.
Meaningless unless considered as a total percentage of the population, and unless compared to the final results.
