There are a number of reasons that 2012 will be completely different from 2008. Conservatives have plenty of evidence against Obama, who finally has a record. The myth of Obama as a moderate was crushed by Obamacare, his anti-business rhetoric, and middle-class tax increases.
No one expects Obama to match his 2008 performance, when people were excited over the historical nature of the race. Now, disenchantment has set in for many, especially those who gave Obama a chance when they otherwise wouldn't vote for a Democrat. Democrat registrations have fallen dramatically, while Republican and Independent registrations have have steadily ticked upwards. At the same time, everyone expects the Republicans and Mitt Romney to do better than McCain did in 2008, not that it would be a difficult task. (Some states, like Indiana, are already penciled back into the Republican win column.)
But the biggest turnaround for Republicans this cycle is the one thing that will enable conservatives to capitalize on these advantages: Money. President Obama is already vilifying the "Republican money machine" and complaining about money in politics in this year's election. Simply ignore that the Obama campaign ran the most expensive campaign in US history in 2008, destroyed McCain in the ad wars, and bragged about wanting to top that and bring in $1 billion this year.
