Mitt Romney won’t be taking another run at the White House, but he may end up being a popular write-in candidate anyway: he leads a recent Fox News voter poll among Republican candidates, and performs the best head-to-head against Hillary Clinton.

The poll, released Thursday, says that the former Massachusetts governor and the loser of the 2012 presidential election is the front-runner to win the Republican Party’s nomination, and Hillary Clinton is also the front-runner for the Democrats. The two come out dead even in the poll, according to a Fox News report.

Romney has 21 percent of the vote among self-identified Republicans in the poll, followed by Kentucky Sen. Rand Paul and Mike Huckabee, former governor of Arkansas, who are both at 11 percent, and finally former Florida Gov. Jeb Bush at 10 percent.

After that, the numbers dip into the single digits for retired neurosurgeon Ben Carson and Wisconsin Gov. Scott Walker, followed by Florida Sen. Marco Rubio. Getting just four percent is New Jersey Gov. Chris Christie, Texas Sen. Ted Cruz and former Texas Gov. Rick Perry.

Romney is also the choice among self-described “Tea Party” members at 20 percent, followed by Carson at 13 percent and then Paul and Walker at 9 percent. He also enjoys the most support among white evangelical Christians.

What happens if Romney drops out, as he ended up doing? Jeb Bush suddenly leap-frogs to the top as voters’ second-choice candidate, followed by Huckabee and Paul.

Clinton still dominates the race for the Democratic Party nomination, although her lead has tightened some what. She now has 55 percent in the poll, compared to 62 percent last month, as Vice President Joe Biden makes some gains, moving up to 17 percent.

In a hypothetical matchup, Romney ties Clinton at 46 percent in the poll, and Clinton performs better against the other candidates, beating them all.
