I really don't buy this argument and even the Great Limbaugh has debunked it time and time again.
That there is a huge swath of "independent" voters "frustrated" with the political process is ludicrous. If the GOP sticks to a strong conservative message, these people will be won over easily. See Reagan's landslides and the 1994 Republican Congressional takeover for examples.
All this talk about "middle of the road," "centrist," and "moderate" is nothing more than DNC/media ruses to move the ideological hash marks further and further to the left.
You misinterpret my posting. Independents do exist, and they want distinct comparisons between GOP and Dems. Most independents vary on social issues, but they want problems solved, low taxes, ethical government, fiancially responsible government, against open borders and etc. These are their common ground with conservatives. When the GOP Congress expands government spending, earmarks and etc, GWB keeps talking about amnesty, GOP senators opposing border fence, the distinction is starting to blurr. If the independents see GOP not much different from Dems, then the Dems and their allies in the MSM will create negative impressions to sway the independents that it is a time for change because life under the Dems will be no different than the current GOP and to take a chance with the Dem opposition.
