The problem answering this is that there are two 'right' agendas.
There's the 'real' agendas which is basically to put all the power and wealth into a very few hands, and wrong a lot of people when needed to do so.
Then there's the 'retail' agenda, the one used to sell the party to the voters, and the one that many Republicans are supporting.
I strongly disagree with the 'real' agenda and can't think of anything I agree with. We could find areas of agreement - like 'global nuclear war is bad', I *think* they have switched to now say that before many advocated a first nuclear strike decades ago - but it's not as if that's a real agenda item for them.
There's a lot more to agree with the retail agenda - the problem THERE is how many things they claim as if the left opposes them when they don't.
For example, the right loves to claim the phrase 'fiscal responsibility'. Now, nevermind the facts that it's the Republicans since Reagan who skyrocketed the debt, the Republicans who created the 'starve the beast' strategy because they found they can't get the people to support slashing programs for the people, so they use massive debt to force cuts. Nevermind it was under Clinton (and a Democratic Congress initially) who took the big Republican deficts to zero. We all say there's a big long-term debt problem.
Republicans also love to say the word liberty belongs to them. They're for Liberty, so the other side hates Liberty. Wrong. But I like Liberty.
Another issue that is confused is defense. The right likes to say they like a 'strong defense'. Well, who doesn't want the US not to be conquered?
The thing is, when you get into massive defense industry corruption and extracting hundreds of billions of dollars, when you get into training and sponsoring death squads overseas for our benefit, when you get into 'wars for power' such as the type PNAC advocated saying you have to trash another country from time to time to remind the world who's boss, those aren't exactly 'defending us from invasion'. So 'strong defense' isn't so simple.
I've long said '95% of what's said here about the left is wrong or lies' - that's the starting point for the discussion, the many straw men the right has.
I think most of us agree on a lot more than many think. Showing right-wing voters that their leaders aren't the benevolent servants they think and the progressive leaders aren't Chairman Mao is needed, not just pretending there's an agreed division of views between the sides.
Don't we all want:
Sensible government programs that help people that we can afford, investments that help our economy, enough defense for reasonable safety from foreign threats, services from the Cineter for Disease Control to raw scientific research to the FBI to enforcement of Civil Rights laws?
Don't we all oppose 'corruption', 'special interest' harming of the public interest, bribery, an excessive 'revolving door', lobbyists writing the laws and getting theirs passed, etc.?
So when Republican retail politics say they 'want excessive regulations removed', what if they're not being honest and calling good regulations that keep their donors from crooked activites? Can't I support what they SAY they want, 'excissive regulations removed', and not the excessive corrupt policy they're pursuing under the false name?
That's why it's not so easy so answer this.
Maybe if each side defined 10 or 20 agenda items for their side and the other side could say what they agree with.
How about TARP? A Bush-created program. Some would say corruptly implemented. So there are at least three positions - for TARP, against TARP, and for a modeified TARP.
Which one of those is the 'right' or 'left' position? It was one of the most significant policies in many years, hard to just say 'oh it's not left-right'.
Let has to distinguish blue dog Democrats from progressives, the right has to distinguish corporatist Republicans from Tea Party people.
