Common pushed things from the republicans such as lowering tax rates, allowing for a school voucher program, reducing regulations on businesses, etc are things that Republicans believe will utlimately have a beneficial impact on the middle class. You disagreeing with that being the case doesn't inherently make it so, nor does it negate the Republicans belief/intent that it will. If you're asking for them to come out and do something specifically "this helps the middle class and only the middle class" then you're likely going to have an issue, because again suggesting such comes from an ignorant and egotistical assumptive stand point that the Republicans must think like some Democrats/Liberals do because that is the only "TRUE" reality. Conservative ideology in general, and republican strategies in general, suggest that the government should not be significantly making it a point to segment off specific segments of the population going "this will help you, this will help you, this will help you", but instead goes off a notion of broad ideas and ideals that are meant to be beneficial to some degree across a wide range of socio-economic groups and also hold that a government limited in it's scope is beneficial to ALL, including the middle class. Simply disagreeing with their belief/intent doesn't make it so, no matter how badly some on the left may be misguided by their own self-indulgent feeling of superiority and absolutism when it comes to their world view.
