The candidates for the Republican nomination for president were in Washington, D.C. on Friday to woo an influential group of voters -- evangelical Christians.

Each of the candidates will speak at the Value Voters Summit, a two-day gathering of conservatives who care deeply about social issues like abortion and gay marriage.

Former Pennsylvania Sen. Rick Santorum, Texas Gov. Rick Perry, businessman Herman Cain, former House Speaker Newt Gingrich of Georgia and Minnesota Rep. Michele Bachmann will all address the gathering on Friday.

Romney and libertarian Rep. Ron Paul of Texas won't speak until Saturday; neither has drawn strong support from cultural conservatives in the past. Former Utah Gov. Jon Huntsman isn't even going to attend.

Bachmann, Cain and Perry have made direct and repeated appeals to the religious right as they pursue the nomination.
