It’s not an exaggeration to say Republicans have bet their future on the disaster they expect from Obamacare. “The implementation of the law over the next year is going to reveal a lot of kinks, a lot of red tape, a lot of taxes, a lot of price increases,” RNC spokesman Brad Dayspring told The New York Times last month. “It’s going to be an issue that’s front and center [in 2014].” GOP intellectuals see Obamacare as the centerpiece of the party’s strategy even well beyond then. “Republicans are likely to seize on every sad [implementation] story as justification for dramatic changes—and in 2016, mount campaigns designed to replace the system in whole or in part with plenty of material to use in their cause,” the conservative wonk Ben Domenech wrote approvingly in March.

And, of course, the party’s base is completely, unremittingly, obsessed with the issue. The mere anticipation of an implementation quagmire is “reinvigorating the movement," Jenny Beth Martin, a national Tea Party official, told The Hill in early May. "We're doing street rallies and protests over the next month to three months, initially. We're working to recruit candidates that can talk about this."

I happen to be agnostic about whether health care implementation will help the GOP in 2014. On the one hand, anything that energizes conservatives in a low-turnout election should benefit Republicans, much as it did on 2010. On the other hand, as The Washington Post’s Greg Sargent points out, much of the public antipathy toward Obamacare is already baked into the polls. The people who disapprove haven’t liked it from the get-go; similarly for the people who approve. It’s possible that a series of implementation snafus will move those numbers at the margins—a new poll suggests public opinion has soured a bit lately, perhaps as a result of all the “train wreck” chatter. On the other hand, it’s also possible that implementation will go relatively smoothly and people will embrace the program, netting Democrats a few more votes.

What I do know is that the GOP’s health care preoccupation is absolutely destroying its long-term prospects. However well the issue may work in the midterms, when an uptick in conservative turnout can flip a few dozen House seats, 2012 proved that it’s at best a wash in a presidential election, when Democrats can swamp that turnout with their demographic edge, and when the GOP’s challenge is to win moderates and independents as a result. Conservatives argue that the only reason health care didn’t work in 2012 is that Romney was a flawed messenger, given his patrimonial link to Obamacare. But with the Supreme Court largely blessing the law last June, the issue was mostly settled in the public mind, making it at best a non-factor among swing voters.

Even if implementation goes terribly, it isn’t like to rekindle widespread angst. Most people will be untouched by implementation—even a disastrous implementation—for the simple reason that they won’t be relying on Obamacare. As Bloomberg’s Josh Barro has explained, 78 percent of us get coverage through Medicare, Medicaid, or our employers, a figure isn’t likely to change very much, or at least very quickly. Meanwhile, my colleague Jonathan Cohn points out that life for many people who do end up on Obamacare will improve, however flawed the program is, because it translates into insurance they didn’t have before.
