Lets see if I can enlighten you.

RINO (Republican in Name Only) is an officeholder or candidate who is a member of the Republican Party, but holds views to the political left of most Republican voters, or simply does whatever the liberal media wants. The term "RINO" describes politicians who claim to be Republican but are in fact liberal or puppets of the liberal media, and therefore generally debase the winning conservative coalition base of the Republican Party.
RINOs are often Republican only to the extent it serves their own interests, and will abandon conservative principles as soon as it is in their own interests to do so. RINOs often provide support for raising taxes, abortion as a right, gay rights and gun control. Some RINOs have connections with Planned Parenthood or corporations that support goals of population control; other RINOs pay lip service to pro-life values while in practice not advancing those values.
Double standards by RINOs are common: a birther comment by Romney during his campaign was supposedly a "nothing", but Todd Akin's pro-life comment would somehow "absolutely" could cost RINOs control of the U.S. Senate!
RINOs, like Democrats, typically come from states in New England, the Mid-Atlantic; or states on the Left Coast. A less-used term is cafeteria conservative, for a person who picks and chooses which conservative principles to believe, as a person might choose foods in a cafeteria instead of ordering the full-course menu selected by the chef at most restaurants. In contrast to RINO's and cafeteria conservatives, movement conservatives understand that since conservative philosophy is a coherent whole, it is untenable to discard part of it without discarding all of it.
