The purpose for bringing up Gingrich and Santorum in the primaries was to point out the dirty dealings of the Republican elites against Conservatives/Libertarians in general within the party. The same type of elites among Republican senators that have been demonizing Cruz and others. You've shown us which side of the bread you have buttered and are in full alignment with the elites. After all, you think Jeb Bush (because he has gravitas) will be the next president and the Republican elites would salivate over such a prospect.
The two seats lost in the Senate, during the 2012 election may mean multiple but that isn't what you were originally getting at when you stated multiple for you included examples of certain races that Republicans lost that you felt they should have won making it greater than just two, an exaggeration on your part. And you also failed to credit the gains in the Senate in 2010 by the Tea Party and their efforts that regained the House. It's amazing what they have been able to accomplish not just fighting their opposition but also those within their own party.
