Many Republicans who are eyeing a run for president in 2016 are backing an all-or-nothing plan to defund ObamaCare.

More than half a dozen possible GOP White House candidates support that strategy while a handful are calling for a more nuanced approach to defunding or repealing the healthcare law. Another five are dodging questions and a couple others are not signaling one way or another.

In short, some are willing to go to the brink and beyond of a government shutdown to defund ObamaCare. But it’s far from unanimous.

Still, the results of The Hill’s survey favors the shutdown-showdown strategy hatched by Sen. Mike Lee (R-Utah), thanks to outspoken endorsements from GOP frontrunners, such as Sen. Marco Rubio (R-Fla.).
