Mitt Romney has retaken the lead in the Republican presidential race following a big win in Florida this week. Can any of the remaining candidates derail his momentum?

This Sunday, Rep. Ron Paul, R-Tex, comes to "This Week" following the Nevada caucuses to make his case for the nomination.

As Rick Santorum and Newt Gingrich vow to stay in the race, how long will Paul keep up his fight for the Republican nomination? Will conservatives coalesce around an alternative to Romney? And will a drawn-out primary fight hurt the eventual GOP nominee?

Republican presidential candidate Ron Paul speaks to George Stephanopoulos, this Sunday only on "This Week."

Then, the latest jobs report shows the strongest employment growth in three years, with 243,000 jobs added in January and the unemployment rate dipping to 8.3 percent.

Or will the recovery be threatened by action – or inaction – by Congress, and turmoil overseas?

Sunday on "This Week," three top economists debate the economy's future: the architect of President Obama's plan, former advisor Lawrence Summers, top Romney economic advisor Glenn Hubbard, and Diane Swonk of Mesirow Financial.

Plus, our powerhouse roundtable with ABC's George Will, political strategist and ABC News political analyst Matthew Dowd, AOL Huffington Post Media Group president Arianna Huffington, and radio host and editor Dana Loesch debate all the week's politics.

Has Mitt Romney cleared the early hurdles in his quest for the nomination? How will the improving jobs picture shape President Obama's political fortunes? And what does Facebook's multibillion-dollar IPO launch signal about today's economy?
