Help me Frame & Develop a Wedge Issue

I could use some help in defining some wedge issues.  I'm going to be giving a speech to a club I belong to that has Dems and Repubs.  I use these speeches to see what talking points seem to work.

I'm in a conservative area, Repubs outnumber Dems.  The tactic I have been working to develop is to make the conservatives doubt their Dear Leader.  

Lately, I've come (stumbled is more like it) upon the theme of "this ain't Eisenhower's Republican Party" anymore (or something to that effect).

Using this as a spring board, I need some examples of what conservative values espoused by Eisenhower Republicans just don't hold water in today's Neo-con world.  Using some themes like this I seem to be getting a response from the moderate conservatives in the audience.  I'm trying to have a cohesive package together by next month for candidates to chew over.

Thanks for the time and I'd appreciate it if you would recommend this for a day so it doesn't spin off of the front page in 30 minutes or less.
