||Strong social conservative base, runner-up in the 2012 primary, by 2016 endorsing RINO-turned-Democrat Arlen Specter will be a distant memory for many because he died in 2012.
||May have been a stalking horse for Romney in the last election, which he'll vehemently deny; in 2016 voters may want a new face to lead the party instead of an also-ran, media portrays as fanatic.
||Says door is open on Presidential bid, compared his 2012 run to Reagan in 1976.
||Favorite of Fox News, articulate, Hispanic, able to win key battleground state of Florida since he's from there, was on Romney's shortlist in 2012.
||Used to be a Tea Party favorite when he defeated RINO Charlie Crist, but many have since soured on his actions, endorses his own version of the DREAM Act, friends with Jeb Bush, denounced Michele Bachmann's investigation into Huma Abedin.
||Visited Iowa in December 2012 to speak at Jack Kemp library.
||Vice-Presidential running-mate in 2012, seen as fiscal hawk, Chair of House Budget Committee, articulate.

||Visited Iowa in December 2012 to speak at Jack Kemp library, named after the man he used to be an aide to.
||Able to win Florida, has Hispanic wife and kids, multilingual, backing of Karl Rove and the Bush family.
||Outspokenly supports amnesty, neither Tea Partiers or independent voters want a third Bush, told GOP primary voters they wouldn't elect Reagan today.
||Might count on Rubio to be a stalking horse because of their friendship, if he and Clinton are the nominees many voters might gravitate to a third party.
||Blunt criticism of teacher's unions won conservatives over for about a year, Ann Coulter supports him.
||Unprofessional style, severely overweight, praised Obama's Hurricane Sandy efforts only days before the 2012 election, has gotten heat for appointing Sharia judge and having pro-abortion Lieutenant Governor.
||First he'll have to get past his re-election campaign against Mayor Cory Booker.

||Pro-choice, ties to Bush administration, never elected to any office, just appointed; left-wing immigration stance, had role leading up to Iraq War, single status will mean she won't have the emotional support of a family for a Presidential run as Laura Bush has said; admired by some conservatives, disliked by others like paleoconservatives and from how Dick Cheney and Donald Rumsfeld have criticized her, she doesn't even have all the neoconservatives wrapped up.
||Some conservatives would think her running would be a good idea, others won't. She declined to run in 2008 and 2012, but from the speculation she was going to be Romney's VP, she might this time.

||Hispanic, fiscal conservative
||Strong record of experience as Governor of Texas. Supports Second Amendment. Before the next election he might see a debating coach. Strong fundraiser.
||Performed poorly in the debates last time, is an also-ran without Santorum's likely momentum in a race that will probably also have multiple of the other Republican Governors, also passed a state version of the DREAM Act and mandated vaccines for schoolgirls.
||He has stated that he might run again.
||Has wanted to be President for decades, has Clinton machine and big money behind her, quitting Secretary of State position lets her run, she will have the 'sexist' card at her disposal.
||Role in Benghazi and decades worth of scandals going back to the 90s, feminist.
