A lot of these GOP governors need to be careful with the congressional GOP. If the economy starts dipping, these governors are not going to be in a good position. They managed to ride Obama's economic improvements as their own (while criticism him) but if the economy of the entire country starts slipping, they'll be blamed.
The GOP is in a really awkward spot. They have a crazy, unpredictable, uncontrollable person as the president. A tea party sipping true believer speaker and a right leaning old school Reagan style "moderate" who talks a hard conservative game as Senate Majority leader. It's like three different, completely unorganized facets of the party and they all want full control.
They're threatening to destroy Obamacare without replacing the parts of the bill that are very popular. They're threatening to get rid of gay marriage, which has bi-partisan support and is probably the fastest way on the planet to get Democrats enthused to beat them. They don't believe in global warming, despite the majority of the country across both parties believing it's a problem. They didn't win the popular vote. They loss house seats. They didn't win because people voted for them, but because nobody voted. They have no mandate to speak of. Many of their governors only have their offices due to Obama's strong economy.
This entire thing is basically set up near perfectly for them to bring in a 2008 style wave for the Democrats. And they know it. They're not stupid. It's a balancing act, and if it teeters off course, it'll be a disaster for the GOP. And losing 2020 in a landslide would crush the GOP for a decade. In sort of a reverse 2010. They got a brief blast of fresh air, but they're still a dying party, only propped up by voter suppression, liberal apathy, and gerrymandering. They know this, and they work towards all three of those things because they can't win without them anymore because America continues to reject their policies, despite them winning elections.
Going to be a weird couple of years for the GOP. It's almost bittersweet for them, absolute power, but with 2020's census year election looming in the distance.
